The screwdriver head is made of S2 steel, which has high strength, hardness (HRC58-60), strong torque, wear resistance and impact resistance, and will not bend or deform after long-term use. The phosphate blackened surface improves corrosion resistance, enhances surface hardness, ensures durability, and is suitable for industrial use.Our drill bit integrates a magnetic design for stable vertical/oblique screw absorption, paired with a high-precision and finely crafted square 4-corner head. Its high-temperature quenched hardness and sharp edges, delivering stable, non-slip operation with exceptional screw fit and impact resistance. Easily install on screwdriver handles, it simplifies work even in tight spaces, significantly boosting efficiency.
