4.2mm x 9.8mm M4 Anti-Loss Washer | 2 Prong | 2.5mm | Nylon

Designed for automotive trim, panels and interior fittings, this M4 pronged washer uses inward-facing prongs to create a retaining grip around a compatible screw or bolt. The Nylon construction keeps the component lightweight and corrosion-free while the 2.5mm thickness suits compact assemblies.

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

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