Product DescriptionOur 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.
Many worldwide projects use our TC bolts, such as Shenzhen
