5mm x 9mm M4 Anti-Loss Washer | 4 Prong | 1mm | Nylon

Made for general industrial fastening, this M4 non-metallic retaining washer provides a simple way to keep a screw or bolt associated with the assembly once fitted. The 4 prong profile flexes around the fastener while the Nylon body provides a lightweight alternative to a metal retaining washer.

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

  • General Maintenance: Reduces the chance of compatible screws or bolts being dropped or lost when equipment is dismantled.
  • Automotive Assembly: Supports retention of fasteners used around trim, dashboards, wiring and interior equipment.
  • 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.
