4.5mm x 8.1mm M4 Anti-Loss Washer | 2 Prong | 2.5mm | Nylon

Providing secure fastener retention for wiring looms and electrical installations, this M4 assembly retaining washer combines a 2 prong design with a 2.5mm section. The natural Nylon construction is non-metallic and helps keep the fastener in place before or after final assembly.

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

  • Manufacturing: Helps reduce loose or misplaced fasteners during production-line assembly and component handling.
  • 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.
  • Automotive Assembly: Supports retention of fasteners used around trim, dashboards, wiring and interior equipment.
