Specially heat-treated S2 steel has better impact resistance and better wear resistance while maintaining high hardness. Black phosphating has better corrosion resistance, can isolate metal from contact with air and moisture, and delay rusting of the substrate.The magnetic screwdriver bit can automatically absorb the screws: when working in narrow spaces (such as inside a chassis or precision instrument) or at heights, it can firmly absorb the screws to prevent them from falling off, and can quickly align the screw holes in blind holes or places with obstructed vision (such as car repair and appliance disassembly and assembly). After being absorbed, the screws are not easy to fall off, reducing the risk of the screws falling into the gaps of the machine or on the ground (avoiding the trouble of disassembly and searching).
