A TENSION CONTROL BOLT(TC BOLT) is a heavy duty plain steel bolt used in steel frame construction. The head is usually domed and is not designed to be driven. The end of the shank has a spline on it which is engaged by a special power wrench which prevents the bolt from turning while the nut is tightened. When the appropriate torque is reached the spline shears off.
Also available in A490 material.
Supplied with nut and washer.
