A stress control bolt is a pre-assembled bolt, nut, and washer used specifically in steel frame building and construction. Likewise known as a TC bolt, they possess a domed head instead of a hex head since they are installed from a spline on their other end. This spline gets in touch with a special power wrench for installation.

Stress control bolts come perfectly pre-lubricated by the maker. They are all set to be installed with a shear wrench. This wrench has an inner and an external socket. The inner socket turns the spline clockwise and the outer socket rotates the nut counterclockwise. When the proper stress has been attained, the spline breaks off.
