Retaining Washers

In stock

A Plastic Retaining Washer are fasteners designed to lock in place after installation - creating a secure fastening assembly. The are designed so the inside diameter grips the outside of a screw shank. The Anti-Loss Washer easily slides on to the screw, but is retained on the screw once assembled.

Our extensive Anti Loss Washer range is available with or without internal teeth. The anti-loss lip is suitable for pre-assembly, which helps reduce final assembly cost and saves time. These Retention Washers come in a wide choice of plastic materials that benefit from excellent sealing capabilities, chemical and corrosion resistance.

  • Materials: Nylon 6/6 and Nylon 6, High and Low Density Polyethylene (PE), Polycarbonate (PC), Polyoxymethylene (POM), and Polyvinyl Chloride (PVC)
  • Colours: Black, Blue, Grey, Natural and Red.

Retaining washers are frequently purchased with our Plastic Standard Hex Nuts by customers.
