Impact Wrench (Impact Gun)
An impact wrench is a powered tool that delivers rapid rotational hammer blows to loosen or tighten tight nuts and bolts.
What is Impact Wrench (Impact Gun)?
It can be air-powered, corded or battery-powered. Workshops often use it to remove wheel nuts quickly. Impact-rated sockets are required, as normal chrome sockets can crack.
How it works
An internal hammer mechanism strikes an anvil repeatedly, creating high torque pulses.
Why it matters for your car
Tightening wheel nuts fully with an impact wrench can over-tighten them and warp discs; the final torque should be set with a torque wrench. Torque-limiting extensions help but are not a replacement for checking.
