What Are Cage Nuts & Why You Need Them

As any IT professional knows, having the right hardware is crucial for assembling server racks and other equipment mounts. One often overlooked but essential component is the humble cage nut. Though small in size, these threaded inserts play a vital role in securing gear inside racks. But what exactly are cage nuts, and why should you use them for your racks?

Cage nuts, also called rack nuts or cabinet nuts, are small metal squares with internal threads and protruding wings. They insert into the pre-punched square holes in rack rails to provide mounting points for screws that fasten equipment like servers, switches and PDUs. The wings on the sides “cage” the nut in place to prevent spinning.

Compared to tapping threads directly into rack rails, cage nuts offer greater durability, flexibility and ease of use. The threaded inserts avoid wear and tear on rack holes. They also let you quickly change mounted equipment without re-threading every time. For tool-less convenience, some cage nuts include a spring-loaded clip or locking tabs.

When outfitting your server rack, network rack or any IT equipment mount, cage nuts should be a essential part of your hardware kit. They allow stable, reliable and adaptable mounting of all your mission critical gear. Plus, finding cage nut suppliers nearby or online is easy.

  • Use the correct screw size for the cage nut’s threads to achieve a snug, vibration-resistant fit.
  • Ensure screws are long enough to extend through the equipment’s mounting brackets but not so long they bottom out in the cage nut.
  • Tighten screws sequentially when installing heavy equipment like servers, not all at once. This prevents lopsided stresses during mounting.
  • Periodically inspect cage nuts and replace any that are deformed, worn or no longer staying firmly retained in rack holes.

Properly installed cage nuts can provide many years of solid, reliable equipment mounting. But even quality hardware requires maintenance checks and occasional replacement.

Cage Nut Sizes – Finding The Right Fit For Your Rack

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

With server racks ranging from shallow network cabinets to extra-deep full-sized racks, you’ll need an assortment of cage nut sizes to accommodate various equipment.

The most common rack nuts are #10-32 thread suitable for mounting smaller networking gear and accessories. For mounting heavier servers and switches, #12-24 thread cage nuts provide greater load capacity.

Nut length is also important for proper fit. 1/2″ fits shallow wall-mount racks, 3/4″ works for most networking racks, while 1″ full-length cage nuts are ideal for deep enclosures.

Consult your rack’s documentation to confirm which thread sizes and lengths its square mounting holes are designed to accept. You want cage nuts that seat flush and tight.

Buying a cage nut assortment kit provides an affordable way to get started. Just beware of ultra-cheap nuts that may split or deform easily under load.

Installing Rack Mount Cage Nuts Correctly With Pro Tips

Installing rack-mount equipment using cage nuts takes just a few steps. But there are some helpful tricks that pros use to get optimal results.

First, loosely thread the cage nuts into the rack’s square holes where needed. Then use a mallet or dead-blow hammer to firmly seat the nuts so the wings lock tightly.

When mounting large devices like servers, gradually tighten opposing corner screws first to level the equipment. Then go back and tighten the other screws down fully.

Spread heavy servers across multiple cage nuts to distribute weight. Also tighten screws incrementally to prevent sudden rack stresses that can deform the framing.

Periodically check cage nut tightness. Vibration can cause previously tight nuts to loosen over time. Snug them up again for a solid mount.

Following these pro tips helps ensure your critical IT equipment stays firmly mounted over the long run.

Solutions For Stripped or Stuck Cage Nuts On A Rack

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

After years of use, rack cage nuts can become stubborn problems. Nuts that spin freely or feel stuck in place make equipment mounting difficult. Here are some ways to deal with troublesome nuts.

For stripped threads, wrap the problem nut with Teflon tape to bulk up the diameter. Then re-insert and use a matching screw. Alternatively, move the mount position to use a fresh cage nut.

To remove stuck nuts, use pliers or Vise-Grips to rock the nut back and forth to break it free. Penetrating oil also helps release stubbornly lodged nuts.

If the rack’s square hole becomes enlarged or distorted, use a washer or external tooth lock washer with the cage nut to take up slop.

In a pinch, you can insert two nuts adjacent to each other at the hole location. Just be cautious not to overtighten and damage the threads.

While it takes a little finesse, most stubborn cage nuts can be repaired or worked around so you can get equipment remounted securely.

Comparing Cage Nut Materials – Steel, Aluminum, Brass or Nylon

Cage nuts come in a variety of base materials, each with pros and cons. Typical options include steel, aluminum, brass and nylon composites.

Steel nuts offer high strength and durability. Stainless steel provides corrosion resistance as well. But steel is susceptible to thread stripping if overtightened.

Aluminum is lightweight but still strong. Anodized aluminum provides good protection in humid server room environments. But aluminum can bend or deform under very heavy loads.

Brass combines corrosion resistance with excellent thread durability. But brass is one of the more expensive cage nut materials.

Engineered nylon or plastic nuts minimize metal-on-metal wear. However, all-plastic nuts lack the durability and load capacity of metal alternatives when used long term.

Consider equipment weight, rack location and budget when selecting the optimal nut material for your specific needs.

Buying Cage Nut Kits For Convenient Server Rack Assembly

Using Cage Nuts to Assemble Server Racks Securely

Putting together server racks and data cabinets is a science – follow best practices and the result is stable, secure equipment mounting. Take shortcuts and you risk loose panels, sagging servers and interrupted operations. Here are pro tips for properly using cage nuts and screws to build robust, reliable racks.

Insert Cage Nuts Correctly

Always loosely thread cage nuts into the square holes on rack uprights first. Then use a rubber mallet to fully seat the nuts so the retaining clips or flanges grasp the hole edges.

Ensure the nut threads face inward, toward the center of the rack. This positions them to accept the equipment mounting screws.

Double check that all cage nuts fit snugly without wobbling before you mount any gear. Spinning or loose nuts won’t hold equipment firmly.

Use Proper Screw Length and Size

Select screws long enough to fully engage the nut threads but not so long they bottom out. About halfway through the nut depth is ideal.

For most racks, #10-32 or #12-24 thread screws work best with correspondingly threaded cage nuts.

Overtightening screws risks stripping the threads. But undersized screws won’t achieve a solid mount. Take your time and find the right combination of screw length and gauge for each nut.

Gradually Tighten Mounting Screws

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

When installing heavy servers and switches, tighten opposite corner screws sequentially to draw the equipment evenly onto the cage nuts.

Don’t fully torque down one screw before moving to the next. Gradually tighten each to avoid uneven rack stresses.

Spread loads across multiple mounting points. Using more cage nuts distributes weight and minimizes deformation risks.

Retighten Cage Nuts Periodically

Vibration can cause previously tight nuts to loosen over time as equipment operates. Frequently inspect for any loosened nuts.

Give nuts a quarter turn tightening to restore a positive grip. Or remove and reseat them for a fresh hold on the rack hole edges.

Loose cage nuts defeat their purpose of keeping gear firmly anchored. Periodic retensioning maintains reliable equipment mounting.

Replace Deformed or Damaged Nuts

Immediately replace any bulging, warped or deformed cage nuts. They can’t provide a robust threaded attachment point.

Also swap out nuts with stripped or crossed threads. Damaged threads prevent secure screw mounting.

It only takes one compromised cage nut to undermine the structural stability of an entire loaded rack. Spotting and changing damaged nuts in time prevents bigger problems down the road.

Following cage nut best practices takes a bit more care upfront. But doing rack assembly right the first time saves maintenance hassles after deployment.

Rushed rack jobs may work initially, but corners cut now result in headaches later. Gradually tighten screws, distribute loads, re-torque routinely, and replace damaged nuts.

Properly installed commercial-grade cage nuts form a critical structural foundation for your server room or data center. A small investment in quality nuts and proper techniques yields big uptime rewards protecting your mission critical infrastructure.

Cage Nut Sizes – Finding The Right Fit For Your Rack

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

When outfitting server racks, having the proper cage nut sizes ensures gear mounts securely. With racks ranging from shallow network cabinets to extra-deep full-size enclosures, you’ll need an assortment of nut sizes to accommodate various equipment.

Shallow Racks

Low-profile racks like wall-mount or open-frame racks often have a mounting depth of 12″ or less. Opt for 1/2″ length cage nuts to avoid exceeding the available space.

10-32 threads are common in shallow racks for mounting patch panels, switches and other networking gear. Nuts with coarse 20 or 24 threads work for heavier PDUs and mini-servers.

Aim for steel nuts rather than softer metals to withstand frequent equipment moves in shallow racks. The 1/2″ length maximizes holding power in the confined depth.

Standard 19″ Racks

For traditional two-post racks with 20″ to 36″ depth, 3/4″ length cage nuts are the typical fit.

Number 10-32 nuts have sufficient thread count for 1U switches and routers. Bulkier servers and SAN storage arrays often require stronger 12-24 threads.

Standard 19″ racks see frequent use, so hardened steel or aircraft-grade aluminum nuts hold up best. The 3/4″ length provides excellent gripping surface.

Extra-Deep Racks

Full-size server racks and open frames extending past 36″ merit cage nuts 1″ or longer to reach equipment mounting holes.

Plus, deep racks often support heavier gear like blade servers and disk arrays. For those loads, choose nuts with coarse 12-24 or 1/4-20 threads.

If the deep rack houses mission critical infrastructure, invest in stainless steel or brass nuts rated for high insertion cycles. The 1″ length maximizes stability.

Cage Nut Assortment Kits

An affordable way to equip any rack is buying a hardware assortment kit with a range of nut sizes and thread pitches.

Look for at least 50 each of 10-32 and 12-24 thread nuts in 1/2″, 3/4″ and 1″ lengths. This provides flexibility for shallow, standard and deep racks.

Complete kits include matching screws and accessories like washers, ensuring all the hardware you need for diverse equipment mounting.

Carefully check nut quality, as super cheap kits often have subpar cage nuts prone to stripping or spinning. Spend a little more for proven commercial-grade hardware.

When in Doubt, Go Longer

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

If uncertain what size nut your particular rack requires, opt for the next longer length to ensure full thread engagement.

For most racks under 30″ deep, a 3/4″ nut allows adequate screw mounting. Go 1″ long for depths exceeding 30″.

It’s better for the screw to bottom out in the nut than to not reach full threading. The nut will still retain equipment securely.

Take time to assess your rack depth and the gear you intend to mount. Then select cage nuts sized to provide rock-solid stability for your critical IT assets.

With the correct nut lengths and thread pitches, you can confidently assemble server racks ready to support demanding network loads. Upgrade or replace any old worn factory nuts to keep equipment firmly planted.

Avoid skimping on proper cage nuts just to save a few bucks. Your expensive rack-mount servers, switches and routers deserve stable commercial-grade steel nuts engineered to securely attach equipment for the long run.

Installing Rack Mount Cage Nuts Correctly With Pro Tips

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

Installing cage nuts may seem straightforward – just twist them into the rack holes. But there are professional techniques that ensure stable, long-lasting equipment mounting. Here are pro tips for getting rack nuts seated right the first time.

Loosely Thread Nuts First

Never force or hammer raw nuts directly into rack holes. That risks damaging threads or retention tabs.

Instead, lightly twist nuts into the desired square holes by hand. Go in straight, not at an angle.

Loosely threading nuts initially allows them to align correctly before being fully seated. Rushing this step causes problems later.

Firmly Seat Nuts in Holes

Once loosely threaded by hand, use a dead blow mallet or rubber hammer to firmly seat nuts.

Several sharp raps should set nuts flush in holes with retaining clips or flanges grasping the hole edges.

Seated nuts shouldn’t wobble or spin. Test each one before mounting any equipment.

Use Torque-Limiting Driver

A torque screwdriver ensures you don’t overtighten screws into cage nuts.

Set torque to the nut manufacturer’s specifications, usually around 25 inch-pounds.

This prevents stripping threads or distorting nuts while still achieving a secure mount.

Gradually Tighten Mounting Screws

When installing heavy servers and switches, lightly tighten opposite corner screws to draw the equipment evenly onto the nuts.

Don’t fully tighten one screw before moving to the next. Go around gradually to prevent rack damage.

Spread Loads

Always use multiple cage nuts to distribute weight for stability.

Mounting large devices on just one or two nuts risks equipment damage or failure.

More mounting points share loads across the rack frame.

Retorque Cage Nuts Periodically

Vibration can loosen previously tight nuts over time.

Every 6-12 months, check for any loosened nuts and retighten.

This preserves reliable equipment mounting as gear operates 24/7.

Following professional rack assembly methods requires a bit more diligence upfront. But doing the job right the first time saves issues after deployment.

Rushing the process may work temporarily, but invariably leads to problems long-term. Take time to properly seat, torque and periodically recheck cage nuts.

Well-installed commercial nuts form a robust foundation for securely mounting server and network equipment worth tens of thousands of dollars. A small investment in quality gear and professional techniques keeps your critical infrastructure firmly planted.

Solutions For Stripped or Stuck Cage Nuts On A Rack

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

After years installing and removing equipment, rack cage nuts can become troublesome. Stripped threads prevent solid mounting while stuck nuts refuse to budge. Here are solutions for remedying problematic cage nuts.

Stripped Nut Threads

Attempting to force oversized or misaligned screws into nuts can strip internal threads, leaving a loose fit.

For minimally damaged threads, wrap the nut with 2-3 layers of plumber’s Teflon tape to slightly increase the diameter. Then re-insert the nut and use proper sized screws.

Heavily stripped nuts require drilling out the damaged threaded hole to remove what’s left of the nut.

Install a new nut into an adjacent hole and use a washer if needed to span any gap created by enlarging the stripped hole.

Spinning Cage Nuts

Nuts that spin freely in rack holes fail to secure equipment. This results from distorted holes or damaged nut wings.

Try compressing the nut wings inward with pliers to improve their grip on the hole edges.

For excessively enlarged rack holes, use an external tooth lock washer behind the nut to take up any slop.

Badly deformed spinning nuts should be replaced. Enlarged rack holes can be bushed to restore original dimensions.

Stuck Cage Nuts

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

Nuts become stubbornly stuck after years in place attracting dust and grime.

Lightly tapping a stuck nut’s edges with a punch can help break it free. Use care not to enlarge the rack hole.

Penetrating oil around the nut’s circumference helps loosen the grip. Let it soak in fully before attempting to remove.

Gripping stuck nuts with Vise-Grip pliers allows added leverage to rock nuts loose. Take care not to damage the nut wings.

Preventing Future Nut Problems

To avoid threaded and retention issues long-term:

  • Clean rack holes thoroughly before inserting cage nuts
  • Always use proper screws sizes for the nut threads
  • Tighten screws gently with a torque driver
  • Periodically inspect nuts for deformation or dust buildup

A bit of preventive care goes a long way to avoiding cage nut headaches. But despite best efforts, hardware issues inevitably crop up over time.

Fortunately, having the right tools and techniques allows correcting pesky nuts quickly and getting equipment remounted securely.

Don’t let minor cage nut problems turn into major racking failures. Addressing stripped, spinning and stuck nuts promptly keeps critical systems running reliably.

Comparing Cage Nut Materials – Steel, Aluminum, Brass or Nylon

Cage nuts come in a range of base materials to suit different rack requirements. Factors like strength, corrosion resistance, conductivity and cost factor into material selection. Here is how common nut materials compare.


Steel cage nuts provide exceptional strength and load capacity for heavy equipment mounting.

Cold rolled steel offers high hardness and tensile strength. Stainless steel adds corrosion and rust resistance.

Plated steel, like zinc or nickel-plated, combines steel’s durability with tarnish protection in humid data centers.

The downside is steel’s conductivity requires grounding racks. It’s also susceptible to thread damage if overtorqued.


Aluminum cage nuts are lightweight while still strong enough for most applications.

Hard anodized aluminum provides excellent abrasion and oxidation resistance in harsh environments.

Aluminum is easy to cut and drill without special tools. It won’t rust or need grounding like steel.

On the negative side, aluminum is softer than steel and can bend or deform under very heavy loads. It’s also more expensive than standard steel nuts.


Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

Brass nuts offer a attractive appearance while resisting corrosion and conducting heat well.

Brass alloys used for nuts provide great strength and optimal threading qualities.

The natural lubricity of brass prevents threads from seizing up. Conductivity precludes using brass nuts with aluminum racks.

The downside is brass costs significantly more than steel or aluminum nuts. Brass is also softer than steel.

Engineered Plastics

Reinforced nylon blends allow non-conductive plastic cage nuts.

Plastic nuts minimize metal-on-metal wear and won’t mar rack surfaces.

Insulative plastic is required for aluminum rack applications. Plastic nuts are also very inexpensive to produce.

However, plastic has far lower strength limits than metal and won’t withstand frequent equipment swapping long-term.

For critical infrastructure, stick with robust steel or aluminum cage nuts. Use plastic for temporary lightweight needs only.

Choosing the best nut material involves tradeoffs between strength, corrosion resistance, conductivity, machinability and cost.

Consider weight loads, rack metals, adjustability needs and budget when selecting nut construction.

While plastics work initially, critical gear merits nuts engineered for the demanding requirements of high-density server rooms and data centers.

Nuts that freely spin or wobble in rack holes can’t provide a stable anchor.

The nut’s locking features are likely damaged or worn away over time.

These nuts must be removed and substituted with new properly seating nuts.

Swap Out Stripped Nut Threads

Attempting to force wrong-sized screws into threads can strip them.

The nut may still stay lodged in the hole, but stripped threads prevent secure mounting.

Drill these out and install fresh nuts for full equipment support.

Change Out Bulged or Deformed Nuts

Need Server Rack Fasteners Nearby. Try These 10 Cage Nuts & Screws

Gradual rack stress can deform thinner low-quality nuts.

Bulged, bent or warped nuts lose strength and stability.

Replace these with robust commercial-grade cage nuts designed for long service life.

Consider Replacing All Factory Nuts

Many equipment racks come with cheap generic nuts preloaded.

After 5-10 years, consider replacing all original nuts as preventive maintenance.

This ensures many more years of solid gear support.

Closely inspecting cage nuts and being proactive about changing worn or questionable ones reduces equipment failures and rack downtime.

Periodically swapping out factory nuts provides inexpensive rack insurance against malfunctions.

Damaged threads or retention systems render nuts ineffective. Don’t wait for failures when problems can be spotted early.

Making cage nut replacement part of regular maintenance saves big headaches down the road. Your critical infrastructure merits secure commercial nuts tested to provide decades of dependable service.
