5Pcs 4Mm Metric Hex Impact Screwdriver Bits 1/4" Hex-Shank 2" Long S2 Steel

The magnetic screwdriver bit is made of S2 steel, which has excellent strength, hardness (HR58±2) and durability. The surface is chrome-plated to enhance its wear resistance, corrosion resistance and rust prevention, and it is not easy to bend, break or deform. The screw driver hex head of the screwdriver is magnetic and easy to use. It can absorb screws stably vertically or tilted, making it easy to fix screws, especially in confined spaces. Precision CNC machined hexagonal head can be in close contact with the screw, making the removal and installation more stable and not easy to slip. The 1/4 inch quick-release hexagonal shank drive head is widely used in pneumatic screwdrivers, hand drills, cordless drills, and manual screwdriver handles. Suitable for furniture assembly, machinery installation, automotive repair, home DIY projects, homemade furniture, woodworking, and more. Note: Before use, please check that it is securely installed on the power tool. Store away from magnetic field and high temperatures to avoid affecting its magnetism.
