StarTech CABCAGENUTS M5 Cage Nuts - 50-Pack

Overview

The StarTech CABCAGENUTS is a 50-pack of M5 cage nuts sized for mounting servers, telecom equipment, and A/V gear into standard square-hole equipment racks. If you're populating a new rack — or backfilling missing hardware on an existing one — CABCAGENUTS gives you enough M5 nuts to outfit multiple rack units without a second order. Cage nuts are the connection point between your rack rail's square mounting holes and the machine screws that hold servers, switches, PDUs, and patch panels in place, so having a deep spare stock on hand keeps a rack build from stalling over a missing $0.30 part.

Key Features

• M5 Thread Type: matches the M5 screw standard used across most commercial and enterprise rack-mount servers, telecom chassis, and A/V equipment — confirm your equipment's screw spec before ordering so you're not mixing thread sizes mid-install.
• 50-Piece Package Quantity: enough cage nuts to fully populate several rack units (typically 4 nuts per U per side), so a single CABCAGENUTS pack can cover a mid-size rack build without reordering mid-project.
• Compact 0.5in x 0.5in x 0.4in Footprint: each nut is sized to snap cleanly into standard square rack-rail punchouts without interfering with adjacent mounting points on dense 1U/2U deployments.
• Silver Finish: a neutral finish that matches typical rack rail hardware, so the nuts don't stand out against the rest of your rack build.
• 7.9oz Total Package Weight: light enough to keep as standing spare stock in a rack-room parts bin without taking up meaningful shelf space.
• Lifetime Warranty: StarTech backs CABCAGENUTS with a lifetime warranty, which matters for a hardware item you'll be reaching into a parts bin for years after the original install.

Integration & Compatibility

CABCAGENUTS is built around the M5 thread standard, the most common cage nut size for enterprise server chassis, telecom cross-connect equipment, and rack-mounted A/V processors. Before ordering, verify the mounting screw spec called out by your specific server, NVR, or network video recorder chassis — some vendors spec M6 or 10-32 instead. If you're planning a rack build from scratch, a PoE and rack planning guide can help you work out how many rack units, and therefore how many cage nuts, the deployment actually needs. CABCAGENUTS pairs naturally with open-frame and enclosed racks carrying PoE switches, NVR appliances, and A/V distribution gear from the StarTech catalog, and it's a reasonable line item to add alongside any new server rack order rather than discovering the gap after the rack ships.

Marty Allison

I keep a pack of the StarTech CABCAGENUTS in every rack-room parts bin I stock. M5 is the thread size you'll hit most often on commercial server and telecom chassis, and 50 pieces is enough to cover a multi-U buildout without a mid-project supply run.

Technical Highlights:

• M5 Thread Type: matches the dominant screw standard on enterprise rack-mount servers and telecom gear, so it fits the widest range of equipment you're likely to be racking.
• 50-Piece Count: at roughly 4 nuts per U per rail side, this pack realistically covers 6+ rack units of hardware in one order.
• 0.5in x 0.5in x 0.4in Size: small enough to seat cleanly in dense square-hole rail punchouts without crowding neighboring mount points.

Deployment Considerations:

• Confirm your chassis screw spec before you order — mixing M5 with M6 or 10-32 hardware on the same rack is a common install-day surprise.
• At 7.9 oz for the full pack, this ships and stores easily as standing spare inventory rather than a per-project consumable.

Reach for CABCAGENUTS when you're populating a fresh equipment rack for NVR appliances, PoE switches, or A/V processing gear and want enough M5 hardware on hand to finish the build in one pass.
