Hytorc® Tension

The latest in stud tensioning, the Hytorc clamp is a hydraulically-actuated mechanical tensioner.

Friction-controlled hydraulic turning of the nut on the bridge provides a precise, calibrated and torsion-free pulling force to the puller connected to the bolt end.

The resulting bolt load and elongation is retained by the nut without load transfer — without consequent bolt relaxation — to within 5% tolerance.

The TUV, ISO and Pressure Vessel certified HYTORC-CLAMP® is ideal for all critical applications, including nuclear, where precise bolt load and joint reliability is a must and where speed and safety is of prime concern.

For less critical or regular applications, Hytorc recommends DISC torsion-free torque.
