A pneumatic screwdriver, also called an impact wrench, is a compressed-air workshop tool used to tighten and loosen bolts far faster than a hand wrench, especially the wheel nuts on a car. Short recordings of it are widely shared online as practical sound effects for automotive videos, repair tutorials and garage montages, where the listener needs to recognise the action instantly. Its popularity comes from that clarity: the whir and rattle need no explanation, so editors keep returning to it for tyre changes, workshop scenes and tool demonstrations.
