Plastic Washers

 (2 product groups)

Plastic washers are used for a variety of applications such as providing a watertight seal, minimizing vibrations, standing up to high electrical requirements, and evenly distributing the load or force of a bolt or screw. One of the most common uses of plastic washers is in electrical and mechanical applications where insulation and resistance to melting, corrosion, and chemicals are required.

Additionally, plastic washers are often used in applications where non-metallic washers are needed to reduce noise and shock or prevent leaks and damage to surfaces.

The specific type of plastic washer will depend on the application's requirements, such as strength, insulation, corrosion resistance, heat or chemical resistance, or aesthetics. Choose from washers such as nylon washers, PVC washers and polyamide washers.

Retaining Washers

In stock In production

Retaining Washers, also known as Retention Washers or Anti-Loss Washers, are primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. They also provide insulation. cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.

This retainer 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. Self retaining washers cold form and fully enter the pitch of the screw to provide improved sealing.

These plastic retaining 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: Polyamide 6.6 (PA) and Low Density Polyethylene (LDPE)
  • Colour: Blue, Grey, Natural and Red
