CNS-02 – M6 Standard Cage Nut Set – Silver – 16mm Thread (Bag of 50)

An M6 cage nut set is a standard fastening method for most 19-inch racks and cabinets with square mounting holes. Each set provides:

• Cage nut – a square nut retained in a spring steel “cage” that clips into the rail.
• Bolt (M6 × 16 mm) – machine screw that threads into the nut to secure equipment.
• Washer – spreads the load and protects painted or plated surfaces.

Function & Use

Rack rails are typically made from thin steel and cannot be threaded directly. The cage holds a replaceable M6 nut behind the mounting hole so equipment can be securely fastened using a standard machine screw.

• Designed for common 9.5 mm × 9.5 mm square punch-outs in rack rails.
• Usually installed using a cage nut tool or flat-blade screwdriver to compress the cage tabs.
• Easily removed and replaced if threads become damaged—no need to replace the rail.

Typical Applications

• Networking: Mounting patch panels, cable managers, PDUs, and switches.
• Servers & storage: Securing rack-mount servers, NAS units, and UPS systems.
• Audio-visual: Installing amplifiers, mixers, and other rack-mount AV equipment.
• Industrial & telecoms: Fixing control equipment in wall-mounted or free-standing enclosures.

Best-Practice Notes

• Always use the washer under the bolt head to protect equipment faces.
• Tighten bolts to manufacturer torque guidelines—overtightening can distort the cage or strip threads.
• Insert cage nuts with the tabs vertical for easier removal in confined spaces.
• Keep spare cage nuts in your toolkit; they are inexpensive and frequently needed during equipment swaps.
• When working in populated racks, use insulated tools to prevent accidental short circuits.
