Each hex screwdriver bit is engraved with the size number for easy identification. Material - Torx head drill bit is made from specially heat-treated S2 steel for superior strength, hardness and durability. The black phosphate coating provides corrosion resistance and reduces friction for smoother operation and longer screwdriver bit life. Features - The tamper-proof hexagonal star screwdriver head is magnetized to absorb screws vertically or tilted, making it easy to remove and install screws in tight spaces. The impact torx screwdriver head is precision-machined to always ensure a tight fit and provide higher torque. The special torque buffer design absorbs vibrations generated during operation, enhances torque transmission, reduces bit wear and extends service life. Application - Magnetic torx head drill bits are designed for easily driving screws into wood, metal and other materials, suitable for furniture assembly, mechanical equipment installation, auto repair, home DIY projects.
