Impact/Torque Wrench: The primary tools used for quickly removing or mounting a center-lock wheel, but they can be used for any wheel really. The impact wrench, not to be confused with an impact driver, is a powerful tool that can exert a high, but measured impact force. Meanwhile, the torque wrench uses leverage and human power to loosen or tighten things to a specific level.
Knock-Off: The old school center-lockers typically used a winged bolt in the center of the wheel that you smacked with a soft-blow hammer to loosen or tighten. They are the forefathers of the modern center-lock wheel and found on many wire-wheel classic cars.
Lug: It’s basically the fastener, typically a nut used to secure a wheel to a vehicle. Most cars have around five lug nuts
