A tension control bolt (TC bolt) is a heavy duty
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
tension is reached the spline shears off.
