American Forge & Foundry 40140 1/2 in Torque Limiting Extension Lt

Torque-Limiting Extension for Wheels

This 1/2 in drive extension stops turning once the preset torque is reached, protecting wheel studs, rims and brake rotors from over-tightening. It is built for tyre shops, fleet depots and general automotive repair where consistent lug-nut torque matters. The maintenance-free mechanism requires no recalibration, so it stays accurate through daily professional use. Color coding and hard-stamped markings make the tool easy to pick from a busy tray.

Suited for Repetitive Lug-Nut Work

Technicians who tighten wheels to the same specification every shift will benefit from the automatic stop that prevents damage and speeds the job. Shops that need a wide range of torque values or drive sizes beyond the single setting this extension provides should look at adjustable torque wrenches or a set of fixed extensions instead. The tool is not designed for general bolt-tightening tasks where torque varies from job to job.

Holds Accuracy Under Continuous Use

Chrome molybdenum steel construction and a powder-coat finish resist wear, chipping and corrosion during high-volume wheel service. The internal limiting mechanism is engineered to deliver the same stop point over thousands of cycles without drifting or requiring service intervals. Heat and vibration from impact guns do not alter the preset value, so the final torque remains consistent from the first wheel to the last.
