M6 Penny Washer - 6.4mm ID x 40mm OD | A2 Stainless Steel

This M6 Stainless Steel Penny Washer is suited to general indoor and sheltered outdoor fastening where a standard flat washer does not provide enough bearing area. Its 40.0mm outside diameter spreads clamping force across more of the surrounding material while the A2 Stainless Steel construction provides durable corrosion resistance.

What Are Stainless Steel Penny Washers?

Penny Washers provide additional bearing area around a threaded fastener. Their broad outer diameter is particularly useful on softer materials such as timber and plastic or on thin sheet where a smaller washer could concentrate pressure too closely around the fixing hole.

Common Applications

  • Plastic Panels: Provides a wider bearing surface around fixings in suitable plastics where pull-through or surface marking is a concern.
  • Automotive Repairs: Provides additional bearing area around suitable fixings used in bodywork, brackets and vehicle components.
  • Marine Equipment: A4 variants suit compatible marine and coastal assemblies where increased corrosion resistance is required.
  • General Engineering: Pairs with compatible bolts, machine screws and nuts across workshop and production assemblies.
