Milwaukee 1/4"&5/16"x6" 2in1 Nut Drvr is designed to be the most durable and cleanable nut driver available. Featuring the innovative QUIK-CLEAR™ cleaning mechanism, it allows for quick and easy removal of metal shavings from the magnet, preventing fastener head stripping for a smoother work experience. This versatile 2-in-1 nut driver combines 1/4" and 5/16" sizes on a single shank, enabling efficient driving of hex head screws across various tasks. Equipped with a powerful magnet that maintains a secure grip without loosening over time, it ensures consistent and reliable fastener engagement. The optimized SHOCKZONE™ shank absorbs peak torque to prevent breakage, while the heat-treated CUSTOM ALLOY76™ steel construction enhances hardness and extends bit life.
