J&R Quality Tools 3/8-Inch Drive Cr-Mo Metric Allen Hex Driver Impact Socket Set, 4 mm - 12 mm | 7-Piece Set

Great tool hold up under full impact gun and the price is better than any body else. P.S. I did have Craftsman but they kept breaking. These are much stronger than expected, I'm very happy.

So far it has been very durable.
