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.

With seemingly limitless varieties of washers available, it is important to select the most optimal type for your specific application. Failure to specify the correct washer can result in machine downtime and lost production.
