The Imada Cedar DI-12-SL15 Automatic Breakaway Torque Tester, 3.0 - 130.0 lbf-in is designed to find the actual yield tightening torque value for specific thread joints which consist of a variety of thread types, multi-layered material, hole sizes, etc. Torque controlled power tools are set to apply consistent torque, but fasteners are not necessarily tightened to that value if the tools are not calibrated. A breakaway test is used to verify the actual tightened torque of a bolt. Breakaway torque tests require a skilled, experienced operator to sense when the bolt begins to breakaway. DI-12 automates this complex operation. Once breakaway torque is measured, power drivers can be reset to the proper tightening torque. DI-12 Automatic Breakaway Torque Tester drives the test piece at consistent speed and detects breakaway torque without overtorquing pretightened fasteners
