1/2 in Torque Limiting Extension

This 1/2 inch drive torque limiting extension stops turning once a specified torque is reached. It is designed for tire shops, automotive repair and fleet maintenance. The tool prevents damage to wheels, studs and brake rotors caused by excessive torque. It suits professionals who need controlled tightening without a separate torque wrench.

Color coded identification

The white powder coat finish provides colour coding for quick size recognition. Hard stamped size markings add a permanent reference that will not wear off. This combination lets technicians select the correct extension at a glance. The coating also resists chipping, scratching and fading in daily shop use.

Chrome molybdenum steel construction

Built from professional grade chrome molybdenum steel for maximum durability and long life. The maintenance and recalibration free design means the tool stays accurate without periodic adjustment. A 1/2 inch square drive fits standard impact sockets and ratchets. Not for buyers who need adjustable torque settings or non impact rated accessories.
