4.2mm x 9.8mm M4 Anti-Loss Washer | 2 Prong | 4mm | Nylon

This M4 component retaining washer is suited to assemblies where fastener retention matters during production, maintenance or repeated access. The 2 prong format grips around the compatible fixing while the 9.8mm outside diameter provides the washer's supporting footprint.

What Are Anti-Loss Washers?

Plastic Anti-Loss Washers use moulded prongs to hold around compatible screws or bolts. Their non-metallic construction makes them useful where a lightweight retaining component is preferred around electrical, automotive and general engineering assemblies.

Common Applications

  • Electrical Equipment: Helps keep compatible screws associated with panels, housings and covers during installation or servicing.
  • 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.
  • Wiring Assemblies: Can retain compatible fasteners around cable management, electrical panels and wiring equipment.
