An impact socket is designed supports the force being applied by an impact gun or ratchet wrench. The wrench sits within the socket, which then attaches to a bolt or nut. Force is applied which can attach or detach the bolt, typically from a wheel on a vehicle. Impact sockets must withstand the vibration this force applies, so are constructed with molybdenum, which creates their distinctive black finish.
