8.4mm x 40mm M8 Anti-Loss Washer | 2 Prong | 3mm | Nylon

Designed for light mechanical assemblies, this M8 retaining washer uses inward-facing prongs to create a retaining grip around a compatible screw or bolt. The Nylon construction keeps the component lightweight and corrosion-free while the 3.0mm thickness suits compact assemblies.

What Are Anti-Loss Washers?

Anti-Loss Washers are retaining washers with flexible internal prongs that grip around a compatible screw or bolt. Their purpose is to keep the fastener attached to the assembly so it is less likely to fall away or become misplaced during installation, maintenance or servicing.

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.
