Our SHOCKWAVE Impact Duty QUIK-CLEAR 2-in-1 Magnetic Nut Drivers feature the Most Durable QUIK-CLEAR Magnet and 2-in-1 size versatility. The QUIK-CLEAR cleaning mechanism allows for fast and easy removal of metal shavings from the magnet to prevent fastener head stripping. The 2-in-1 nut driver design offers two nut driver sizes on one shank to allow for maximum versatility when driving hex head screws on the jobsite. The QUIK-CLEAR 2-in-1 Magnetic Nut Drivers feature a powerful Impact Duty magnet that prevents it from loosening over time to enable a consistent secure grip and unyielding fastener engagement. The optimized SHOCK ZONE absorbs peak torque and prevents bit breakage. Made from heat treated CUSTOM ALLOY76 steel to control hardness and extend bit life. The nut drivers feature two color-coded rings for quick and easy size identification. Designed for use with impact drivers and drill drivers.
