5mm x 8mm M5 Anti-Loss Washer | 4 Prong | 1mm | Nylon

This M5 anti-loss washer uses a 4 prong profile to help retain a compatible fastener during assembly, servicing and handling. With a 5.0mm internal diameter, 3.30mm grip diameter and 8.0mm outside diameter, it provides a compact non-metallic retention solution for machinery covers and service panels.

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

  • Wiring Assemblies: Can retain compatible fasteners around cable management, electrical panels and wiring equipment.
  • Electrical Equipment: Helps keep compatible screws associated with panels, housings and covers during installation or servicing.
  • Manufacturing: Helps reduce loose or misplaced fasteners during production-line assembly and component handling.
  • Machinery: Provides a simple retaining component for screws used on guards, covers and light mechanical assemblies.
