Flat Washers

Flat washers have a simple and effective design that evenly distributes load and prevents fasteners from loosening. These thin disc fasteners come in a broad range of styles, diameters, and thicknesses for light-duty and heavy-duty applications.

We stock durable, structural steel fasteners from brands you recognize and trust. Options include square washers, plate washers, F436 washers, SAE washers, and much more. Sizes range from ¼” to 1-1/2,” with a choice of mild steel, A325 structural steel, zinc-coated steel, galvanized steel, or stainless-steel material.
