IRWIN lobular nutsetters drive a hex head fastener on its flats rather than forcing the corners to turn, which keeps the head in shape and reduces stripping. The rare earth magnet holds the fastener on the tool while you start it, and the 1/4" hex shank drops straight into a quick-change chuck.

• Fits 5/16" hex head fasteners
• 1-7/8" overall length
• Lobular design reduces stripping damage by driving the fastener on the sides instead of forcing the corners to turn
• Provides more clearance on the corners of the fastener, where paint build-up can occur
• Rare earth magnet is 4X more powerful than a common magnet
• For use with sheet metal screws and other hexagonal head fasteners
• S2 tool steel construction
• 1/4" hex quick-change shank
• IRWIN part no. IWAF242516

Tip: Seat the fastener fully in the socket before running the driver so the magnet, not your second hand, does the holding.
