- Our hardware is sold by weight not by actual piece count. Actual quantity may vary slightly.
Rubber washers are used as “lock washers” or retention spacers for your hardware connections. You place them between the two parts to be joined and they compress to provide some tension on the hardware to help keep it from backing out. They also help cushion the joint and prevent stress from transferring from one part to the next. We have these custom made just for us right here in the U.S.
