5/32 Inch Zinc Plated Steel Back-Up Washer


Back up washers are flat washers for rivets. They provide a larger circular bearing surface which helps prevent a rivet head from pulling through the material.
  • Use back up washers when the hole size or the grip range is out of suggested specification
  • Also serves as an excellent bearing surface in thin sheet metal or plastics
