IRWIN Impact Performance Series lobular nutsetters are built for durability and long life with impact tools. They drive the fastener from the side rather than forcing the corners to turn, which keeps the head in shape and cuts down on breakage and stripping. The 1/4" quick-change shank is made for impact drivers and also resists slipping in a standard drill chuck.

Tip: Seat the fastener fully in the socket before pulling the trigger, and ease off as the head lands so the driver does not keep hammering a seated fastener.
