Mark-10 Series TT02 Torque Tool Tester

Bench tester that audits torque screwdrivers and wrenches

This tests the tool itself rather than a workpiece. Plug a torque screwdriver or wrench into the 3/8-inch square receptacle and turn it, and the tester reads the torque the tool actually delivers — manual, electric, or pneumatic. It captures both first and second peak, the signature a click-type tool produces, so you can see the torque at which the click occurs.
