Tension Control Bolt

Tension Control Bolts (Torque Shear Bolts) and the innovative Shear Wrench system are the lowest cost method of properly installing High Strength Friction Grip/ Pre-loaded Bolts..

These are improved type of heavy hexagonal structural bolts, were developed for more simplified bolt fastening and more accurate performance and offer such excellent characteristics as shown below because no fastening technique of high level is required :

Installation Procedure
The bolt reacts to the fastening torque and the notched end of the bolt shears off.

The required clamping force is thus given.
1) Controlled clamping force can be ensured.
2) Completion of bolt fastening can be confirmed by the shear-off of the notched end of the bolt.
3)  Fastening can easily be done by electric wrench.
4) Noiseless installation and no need of wrench adjustment.
5) The bolt does not rotate when fastening.
6) No apprehension of bolts being left unfastened.
