M6 x 16mm rack-mount hardware kit

The 60-piece set supplies M6 screws, square cage nuts and washers sized at 16 mm for mounting standard rack-mount equipment into server racks or cabinets with square holes. It is aimed at installers who need a complete fastener pack for 1U to 12U enclosures. Black nickel-plated carbon steel resists corrosion in typical data-centre environments.

Square-hole cage-nut constraint

The square cage nuts only engage racks or cabinets that have square mounting holes; they will not fit round-hole or threaded-hole rails. Each nut accepts the included M6 thread, so the hardware is limited to equipment that specifies M6 mounting. No other thread sizes or hole patterns are supported by this pack.

Tool-free nut insertion and common issues

Cage nuts press into square holes by hand, while screws drive with a standard Phillips bit, making installation straightforward for a single technician. The most frequent problem is misaligned cage nuts that spin in oversized or damaged square holes, preventing the screw from seating. Ensuring the rack holes are undamaged and fully square avoids this issue.
