3Pcs 5/32" 3/16" 7/32" Hex Screwdriver Bit Set, SAE 4" Length

The hex power screwdriver bits are made of S2 alloy steel, offering high hardness and the ability to withstand greater torque; sandblasting treatment enhances their corrosion resistance. The magnetic tips easily attract screws during use. The screwdriver bits are precisely sized with markings on the surface for easy identification. The chamfered tip allows for smooth insertion into fasteners and protects both the screwdriver bit and the fastener from edge damage. This magnetic hex impact driver bit works with hex shank electric screwdrivers, impact drivers, hand wrenches, and power tools. It quickly drives and removes screws of various sizes, suitable for DIY hand-making, furniture assembly, household appliance repair, and hardware maintenance, and is widely used in home improvement, workshop projects, mechanical repair, and professional trades. Note - Do not turn the screws with mismatched size to avoid damage to both the screw and the drill.
