Irwin 3548521C Magnetic Nut Setter, 3/8 in Drive, Lobular Drive, 2-9/16 in L, 1/4 in L Shank, Hex Shank

Irwin lobular nutsetters are designed to drive the fastener from the side, rather than forcing the corners to turn, maintaining the true shape of the fastener and dramatically reducing breakage and damage from stripping. The lobular design also provides more clearance on-the corners of the fastener where paint build-up often occurs. They are manufactured with powerful rare earth magnets that hold fasteners securely in place and a 1/4 in quick-change shank that works in all-types of drills and drivers.
