Washers are a vital component of many fastened joints. Washers are critical to the operation of virtually every device with moving parts. They perform a variety of functions beyond just securing bolts, nuts, screws and rivets. They can insulate, seal, lock, provide spacing, improve appearance, supply spring force, align parts, and distribute loads.

To the general public, a washer is just a cheap metal disc that keeps screws, bolts, and nuts tight. But to manufacturers, a washer is a vital fastening component, specially designed to perform unique functions and ensure a reliable bolted joint.
