CLAMP® How does it work?

The HYTORC-CLAMP is the first mechanical tensioner that permits accurate bolt load setting without diverting to torque or pulling force. The HYTORC-CLAMP consists of a washer and a nut connected to an inner sleeve that is connected to the bolt end. When the inner sleeve is held stationary by the tool that turns the nut, the inner sleeve is pulled up along the bolt, -torsion- and side load free.

As the nut turns on the washer and the inner sleeve-thread at a know coefficient of friction, the residual bolt load or pre-load can be calibrated in a traceable way with an unprecedented accuracy of +5%.

The HYTORC-CLAMP is ISO, TUV and Pressure Vessel certified.
