Structural Washers are medium carbon steel, heat treated and hardened to 35-41 HRC. Structural Washers are for use with Structural Bolts and are designed for steel-to-steel structural connections such as buildings and bridge construction.

What does a structural washer do?

Washers have traditionally been used to protect the joint surface from damage during the tightening process and to distribute the load under the bolt head and nut. The stress under the face of a standard hexagon headed nut can result in indentation into standard strength steel surfaces.
