## Long description

Screw locking fastener SCHROFF model 21101847 is supplied as a pack of 100 pieces and is designed to secure screws against unintentional loosening in electronic racks, server cabinets and industrial enclosures. Each fastener features a locking head that retains the screw reliably under vibration and thermal cycles, helping maintain mechanical and electrical connections in equipment assemblies.

How to use
Place the locking fastener over the screw head or into the designated mounting feature according to the equipment design, then tighten the screw to the specified torque for the application.
