Typical tension control bolts. The internal socket on the shear wrench grips the spline feature at the far end to counter the torque applied while tensioning the bolt, then twists it off.

Click-type torque wrenches are pretty simple at the core, with a spring and mechanism that shifts with a certain level of force. That spring is the key to calibration, so keeping it under tension ...

We tested a range of impact wrenches—from a heavy-duty, high-torque model down to a compact, medium-duty model—and subjected them all to the same challenges to identify their strengths and ...

Designed to deliver high torque output with minimal effort ... The Ingersoll Rand 2235QTiMAX is a pneumatic air impact wrench with a twin-hammer mechanism. Its lightweight titanium construction ...
