What tool is used in combination with an impact wrench to install lug nuts on wheels?

• A. Torque Wrench Extension
• B. Impact Sockets
• C. Torque Stick
• D. Lug Nut Socket

Answer: (C)

Controlling torque when installing lug nuts with an impact wrench is the concept here. A torque stick is a torque-limiting extension that you attach between the impact wrench and the lug nut. It has a rated torque value, and as the fastener approaches that limit, the stick flexes or stops delivering additional tightening. That prevents the wrench from applying more than the set torque, helping avoid over-tightening, which can stretch threads, warp the rotor, or pull the studs. This approach works well because impact wrenches can produce a lot of instantaneous torque, and the torque stick provides a safe upper bound tailored to the wheel’s spec. After using the stick to bring the lug nut close to the required torque, many technicians will still verify with a calibrated torque wrench to ensure exact spec. The other options don’t serve this limiting function. A torque wrench extension changes reach but doesn’t limit torque. Impact sockets and lug nut sockets are designed to withstand impact and fit the fasteners, but they don’t regulate how much torque is delivered.
