Flat Washers - Plastic

In stock

Flat Washers made from a variety of plastics. Also known as plain washers, these flat plastic washers are among the most commonly used. The plastic washer helps evenly distribute the load of a fastener, such as a nut, whilst helping to reduce heat and friction during the process of tightening.

Our wide range features a vast array of sizes, including large diameter plastic washers that are suitable for a number of metric threads. We also offer a choice of materials, including Nylon washers and other plastic washers made from Polycarbonate (PC), Polypropylene (PP) and Polyoxymethylene (POM). As well as high-quality, hard plastic washers like Polyether Ether Ketone (PEEK). All with a durable, smooth finish.

  • Insulates against moisture and electricity
  • Resistant to corrosion, abrasion and most chemicals
  • Provides full insulation, cushioning and spacing
  • Colours: Natural, Black and Brown.
