4.3mm x 10mm M4 Anti-Loss Washer | 3 Prong | 0.8mm | Nylon

This M4 component retaining washer is suited to assemblies where fastener retention matters during production, maintenance or repeated access. The 3 prong format grips around the compatible fixing while the 10.0mm outside diameter provides the washer's supporting footprint.

What Are Anti-Loss Washers?

Pronged Retaining Washers are fitted over compatible fasteners to create a light interference grip around the shank or thread. This helps keep screws and bolts associated with panels, covers and equipment where the fastening point may be opened repeatedly.

Common Applications

  • Electronics: Provides a lightweight retaining washer for screws used in housings, boards and equipment assemblies.
  • Service Panels: Keeps screws with removable covers or access panels when they are opened for inspection or maintenance.
  • Instrumentation: Helps keep small fasteners attached to equipment housings and adjustment assemblies.
  • Electrical Equipment: Helps keep compatible screws associated with panels, housings and covers during installation or servicing.
