General Purpose Washers

General Purpose Washers are the most versatile fasteners used to distribute the load of a threaded bolt, screw, or nut while reducing friction and preventing surface damage. Available in standard SAE, USS, and metric sizes, our general-purpose washers are crafted from materials ranging from zinc-plated steel to corrosion-resistant stainless steel. They are essential for everyday construction, maintenance, and repair tasks, providing a stable bearing surface and ensuring consistent clamping force across a wide variety of industrial and commercial projects.
