1/2 in. Drive 140 ft. lbs. Torque Limiter
This torque limiting extension bar is designed for automotive technicians and DIY mechanics who use impact wrenches to tighten wheel lug nuts or other critical fasteners. It prevents over-torquing by flexing internally once the preset limit is reached, protecting threads and components from damage.
Installation and common issues
Attach the bar between your 1/2 in. drive impact wrench and the socket; no calibration or adjustment is required. The most frequent error is using the bar with a breaker bar or ratchet instead of an impact wrench, which prevents the internal mechanism from activating correctly. Always verify the color-coded ring matches the 140 ft. lbs. specification before use.
140 ft. lbs. (190 Nm) torque limit
This single value determines whether the bar suits your application; it must match the exact torque specification called for by the vehicle or equipment manufacturer. If your required torque is higher or lower, this extension will not provide the correct clamping force. The 8 in. length and Chrome Molybdenum steel construction support this fixed limit.

Questions about this item
How can I verify the extension bar is limiting torque to 140 ft. lbs. after fitting it to my impact wrench?
The bar is engineered to stop delivering force once 140 ft. lbs. (190 Nm) is reached, so the fastener will no longer turn tighter when the limit is hit; you can confirm by checking that wheel nuts or similar fasteners match the vehicle specification with a calibrated torque wrench afterwards.
What comes in the package and do I need to buy a 1/2 in. drive impact socket separately?
The package contains the single 8 in. torque limiting extension bar with its colour coded ring; a compatible 1/2 in. drive impact socket for the fastener size you are tightening must be supplied separately.
Why choose the 140 ft. lbs. version instead of a different torque limit?
Select this 140 ft. lbs. (190 Nm) bar when the fastener specification calls for that exact torque value; using a bar with a higher or lower limit would over tighten or under tighten the joint.
