Irwin Impact 3/8" x 100mm Magnetic Nutsetter

The lobular design Irwin Impact Magnetic Nutsetter drives the fastener on the side instead of corners, resulting in less stripping and longer life. The rare earth magnets hold fasteners securely with four times the hold of standard magnets. With a 1/4" quick-change shank, it is designed to work with impact drivers, and reduces slipping in standard drill chucks.
