4.2mm x 9.8mm M4 Anti-Loss Washer | 2 Prong | 3.5mm | Nylon

Made for general industrial fastening, this M4 non-metallic retaining washer provides a simple way to keep a screw or bolt associated with the assembly once fitted. The 2 prong profile flexes around the fastener while the Nylon body provides a lightweight alternative to a metal retaining washer.

What Are Anti-Loss Washers?

Retaining Washers provide a simple captive-style fastening aid without permanently fixing the screw to the assembly. The internal prongs flex over the fastener and resist it dropping free which is useful during production, transport and maintenance.

Common Applications

  • Instrumentation: Helps keep small fasteners attached to equipment housings and adjustment assemblies.
  • General Maintenance: Reduces the chance of compatible screws or bolts being dropped or lost when equipment is dismantled.
  • Electronics: Provides a lightweight retaining washer for screws used in housings, boards and equipment assemblies.
  • Domestic Appliances: Supports fastener retention around appliance covers, internal fittings and maintenance points.
