CAYMON M5 Cage Nut KM500 — cage nut for M5 threaded studs, steel mounting hardware

CAYMON M5 Cage Nut KM500 is an M5 cage nut engineered to provide a captive M5 threaded insert inside a spring steel cage for mounting equipment into square or pierced rack rails and panels. Designed for compatibility with standard rack-mount hardware, the KM500 ensures a secure threaded anchor point where welded or threaded rack holes are not available. The product is suitable for use in server racks, AV cabinets and other general-purpose rack installations that require M5 fasteners.

Advantages

The KM500 combines a hardened M5 threaded insert with a resilient spring steel cage to hold the nut firmly in place during installation. Its captive design prevents the nut from falling out when aligning equipment, and the spring action accommodates slight variations in rack rail thickness. Constructed of steel for mechanical strength and durability, this cage nut offers reliable thread engagement for repeated mounting and removal of devices.

Suitable for

• Mounting servers and network equipment into square or perforated rack rails
• Attaching AV components and patch panels in audio/video cabinets
• Securing brackets, shelves and accessories where M5 threaded fastening is required

Key specifications

• Thread size: M5 captive threaded insert
• Body material: spring steel cage with steel threaded insert
• Finish: raw or plated steel finish suitable for mechanical installations
• Mounting type: captive cage nut for insertion into square or pierced rack rails and panels
• Compatibility: designed for standard rack holes that accept captive cage nuts

How to use

Position the KM500 cage nut so the spring steel wings align with the rack rail hole or panel opening, then compress the cage slightly and insert it into the square or pierced hole until it snaps into place. Once seated, thread an M5 screw through the equipment flange and into the captive insert, tightening to the required torque for the mounted device. To remove, unfasten the screw and depress the cage wings to release the nut from the rail.

Usage recommendations

For reliable mounting, use M5 screws of appropriate length and strength for the equipment and rack rail thickness; avoid over-torquing to prevent thread damage. Inspect cage nuts for deformation before reuse and replace any units that show wear or corrosion to maintain secure attachments.
