Impact Driver Bit Set 5/16in Hex 6pc for Air Hammer Guns

An impact driver bit set for air hammer guns, made for shifting seized screws and stubborn small fasteners more quickly than a hand impact tool. This 6-piece impact driver set includes 5/16in hex impact bits and a holder that can also be turned with a 19mm or 3/4in open end spanner while the fastener is being impacted.

Used for vehicle maintenance, workshop repairs and general fastening work where screws have become tight, corroded or difficult to remove. It is especially useful for seized brake rotor screws, but also suits other small fixings where extra turning force and repeated impact help free the fastener without relying on a manual impact driver alone.

The included bit selection covers common crosshead sizes from PH1 to PH4 along with an 8mm slotted bit, giving a practical range for different screw heads. The 5/16in hex fit is suited to this type of impact setup, and the holder design allows added control by using an open end spanner as you work. That makes it a useful option for regular garage and servicing jobs where awkward or seized screws come up more than once.
