Washers are designed for assembly around a bolt or screw, between the bearing surface or the fastener and the part which it is attached. Flat washers are used to improve stress distribution, and span large clearance holes. Locking washers are used to resist loosening caused by vibration and corrosion. I.T.P. sells USS, SAE, and Fender washers by the pound.
