An excellent replacement for lost, bent, or broken hexagon screwdriver bits. Those screwdriver bits are made of S2 alloy steel material with sandblasting finish, high hardness and durability, suitable for industrial use. The magnetic screw holder ring can magnetize screwdrivers, bits, hex key wrenches, etc., easily and quickly grab the screws and fix them, reducing wear and improving work efficiency. The drill bit set can be matched with an interface 1/4" torque wrench, ratchet wrench, slide bar, power wrench, and drive square head. 1/4-inch hexagonal bits feature a positioning nut, adjusting screw rod, and lock nut, a good helper for DIY hand-making and household maintenance.
