Penny Repair Fender Washer

Repair Washers have a particularly large outside diameter 

Repair Washers are used with threaded fasteners (for example a bolt and a nut), designed to increase the load distribution.

  • Mudguard (fender - USA term) washers have an extra large outer diameter to either spread a load more or to straddle a damaged/ oversized hole.
  • Typically used to spread the tightening load over a greater area than a conventional flat washer.
