Hi-Collar Lock Washers Distributor
Washers provide a smooth bearing surface and are used under the head of a bolt and/or a nut. They help to create a larger, smooth bearing surface for the nut and/or bolt.
A washer is a thin plate with a hole that distributes the load of a threaded fastener, such as a screw or nut. They are also often also used as spacers. Washers usually have an outer diameter (OD) about twice the width of their inner diameter (ID).
High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to Brinelling after the torque is applied. Bayou City Bolt, leading Hi-Collar Lock Washers Distributor, can provide your company with this and so much more. Give us a call today to learn more about our metric flat washer
