Retaining Washers

In stock

A Plastic Retaining Washer is primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. Also known as an Anti Loss Washer, they provide insulation, cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.

This washer range includes options with internal and external teeth with a tapered design. The washer easily slides on to the screw (or bolt) and is retained by the screw once assembled. The washer cold forms and fully enters the pitch of the screw to provide sealing.

These washers allow for preliminary mounting of the screw (or bolt) before securing with a nut. They are ideal when pre-assembly of the screw and washer is required. They also help reduce assembly time and cost.

The range includes material options that provide corrosion, abrasion and chemical resistance.

  • Materials: Polycarbonate (PC), Polyamide 6.6 (PA) and High Density Polyethylene (HDPE)
  • Colour: Natural
