The nut driver drill bit tool is engineered to deliver precise engagement with hexagonal socket screws and bolts. Constructed from 40Cr alloy steel, it ensures durability, toughness, and mechanical strength, while the phosphate black surface treatment further enhances hardness, wear resistance, and corrosion protection for long-term reliable performance.The power nut drivers feature a magnetic tip, ensuring screws and bolts are securely held in place for effortless and precise application. The hexagonal design helps achieve a solid grip and effective torque transfer from the tool to the fastener, reducing the effort needed. 1/4 inch quick-change hex shank nut driver sockets are suitable for tasks that require precise driving of hex nuts and bolts, such as assembling furniture, machinery repairs, and automotive maintenance.
