Plastic Flat Penny Washers (DIN 9021)

Plastic Flat Penny Washers, to DIN 9031 standard or ISO 7093, are one of the most adopted forms of washer on the market – commonly known as Fender Washers or Repair Washers.

They host a large outside diameter compared to other types, typically three times the size of the inner diameter. This provides an increased bearing surface to distribute loads evenly, helping to prevent wear and distortion of the installation surface.

Suitable for use with any matching screw or bolt, they can function as spacers or cushioning washers within an assembly and are ideal for use with a worn or rusted hole.

Often utilised within applications to prevent friction or where shocks and vibrations may cause damage to components.

Manufactured from Nylon 66 (PA 66) as standard. This provides a strong, lightweight washer featuring good corrosion and chemical resistance.

Supplied in a White (natural) colour as standard – these Plastic Flat Penny Washers to DIN 9031 can be dyed on request to best suit the intended application or assembly.

Available now for thread sizes from M2.5 (2.7mm) to M20 (22mm), with other sizes available to order – minimum order quantities apply.

Non-standard sizes, materials and colours are available to order as specials, including small volume manufacture, modifications and custom parts made to drawings.

We supply a range of Plastic & Nylon Washers here at Fastenright.
