M8 Penny Washer - 8.4mm ID x 55mm OD | A2 Stainless Steel

Manufactured for plastic panels and softer sheet materials, this M8 Stainless Steel Repair Washer measures 55.0mm across the outside with a 8.4mm internal diameter. Its wide flat profile increases the contact area around the fixing which is useful on timber, plastics and thin sheet materials.

What Are Stainless Steel Penny Washers?

Also known as repair washers, Stainless Steel Penny Washers sit beneath bolts, machine screws or nuts to enlarge the load-bearing surface of the joint. This can help prevent fastener heads or nuts from digging into the material or pulling through it.

Common Applications

  • Automotive Repairs: Provides additional bearing area around suitable fixings used in bodywork, brackets and vehicle components.
  • Machinery Maintenance: Provides a broad replacement washer for suitable bolts and machine screws on industrial equipment.
  • General Engineering: Pairs with compatible bolts, machine screws and nuts across workshop and production assemblies.
  • Thin Sheet Metal: Supports fasteners across a larger area around holes in thin fabricated sheet and panel materials.
