Tension Control Bolts are pre-assembled bolt, nut and washer designed for use in steel frame construction. The head of the bolt is usually domed, and the end of the shank has a spline to which a special power wrench is attached. When the pre-lubricated nut is tightened, the spline fractures when the correct tightening torque is achieved. Tension control bolts are covered under ASME Standard B18.2.6
