Construction Washers for Structural Steel, Sheet Metal, & Woodworking Applications
Flat Washers
Flat washers are placed under the head of a bolt or nut to provide a smooth bearing surface and evenly distribute loads. Available in diameters ranging from 1/4” to 3” and in a range of finishes, including 18-8 stainless steel, 316 stainless steel, galvanized steel, plain steel, and zinc-coated steel.
Structural Washers
Structural washers are designed for use with A325 structural bolts, studs, and nuts used in heavy duty construction or exterior building applications. Available in diameters ranging from 1/4"x5/8” to 1-3/4”x3-3/8”. Choose from galvanized steel, plain steel, or zinc coated steel finish options.
Fender Washers
Fender washers have a large outer diameter compared to the inner diameter, allowing them to evenly distribute loads over large surface areas—usually thin metal. Available in diameters ranging from 1/8”x3/4” to 1/2"x2”. Material options include black-oxide steel, 316 stainless steel, 18-8 stainless steel, zinc and zinc yellow-chromate plated steel, and hot-dipped galvanized steel.
Plate Washers
Plate washers are used in woodworking applications to prevent the heads of bolts or nuts from pulling into the wood. Available in diameters ranging from 3/8”x2”x3/16” to 1-1/2”x6”x3/8”. Finish options include either plain steel or hot-dipped galvanized steel.
SAE Washers
SAE washers comply with specifications set by the Society of Automotive Engineers, often featuring smaller outer diameters and thinner gauges compared to U.S. standard washers. Diameters for SAE washers range from 1/4” to 1-1/2”. Available in hot-dipped galvanized steel, zinc-coated steel, or plain steel.
Split Lock Washers
Split lock washers are helical shaped, split rings designed to prevent fasteners from loosening in applications involving vibrations. Split lock washers are available in diameters ranging from 1/4" to 2”. Choose from hot-dipped galvanized steel, zinc-coated steel, or plain steel finish options.
