Fender Washers Light Fender Washers
Fender Washers were originally developed for automotive body repair. They are presently used more in sheet metal, electrical, plumbing, dry-wall and wood paneling applications... where an extra-wide bearing surface is required for installation of fixtures, etc. Fender Washers also have become so popular for attaching signs to posts, walls, etc. that they are also known as "sign washers". Made of thin gauge steel, they are referenced several styles which relate to their relative outside diameter: very small ,small, regular, large ,extra large
