Get Easy Test Results
A simple way to test the shear torque of weld studs. Apply a straight pull of the WSTT wrench (no side load). When the wrench breaks-over and the weld stud is still attached then it
passed. If the weld stud breaks off - then it failed.

The setting adapter is used for setting the torque of the
WSTT with a torque analyzer. The Setting Adapter features a 3/8” square drive on one side. The other end features a blank end so you can weld the appropriate weld stud.
