Review on Steelman 1/2-Inch Drive 100 ft-lb Impact 🔧 Wrench Torque Extension, 8-inch Length, Gray, Corrosion-Resistant Powder-Coated Steel by Sean Reddy

Tested with an impact wrench and the torque limiter stops within 2 pounds of advertised torque. After stopping, the torque was measured with a torque wrench. This must be used with an impact wrench. This extension twists upon impact and the degree of twist increases as torque increases. At the end, the extension cord twists so much that the outlet doesn't move. This is a simple explanation of how it works. Note that this torque limiter will not work with a regular socket wrench as the force applied is constant and does not have brief bursts or bumps.
