High-hardness alloy steel screwdriver and drill bits designed for durable, precise fastening of high-strength screws. Key benefits Built for strength: Wear-resistant, alloyed steel with high hardness delivers long life and reliable performance on high-strength screws. Secure, slip-resistant engagement: Cross (Phillips) bit features a slip-resistant design for safer driving and reduced slipping during use, improving control and precision. Quick installation and removal: Hex (six-sided) screwdriver bit is easy to mount and dismount, saving time on set-up and bit changes. Impact-capable performance: Impact-resistant bit construction withstands repeated hammering from impact drivers and hand tools while maintaining accuracy. What makes it stand out Durable material: All bits are made from alloyed, wear-resistant steel engineered for hard service. Versatile compatibility: Works with manual screwdrivers, cordless screwdrivers/drivers, and hand-held drill drivers — suitable for both hand and powered applications. Multi-function set: Includes cross (Phillips), hex (six-sided) and impact-rated bits to cover common fastening needs without changing tool types. Practical features Function: Reliable driving of high-strength screws with improved grip and precision. Compatibility: Designed for use in screwdrivers, cordless drivers (accu drivers), and hand drill machines. Performance: High hardness and wear resistance for extended service life; impact-resistant design resists deformation under heavy use. Use scenarios Furniture assembly: Securely drive high-strength screws into dense boards and frames without bit slipping or premature wear. Light automotive and equipment repair: Fasten or remove machine and vehicle components that use tougher screws, using an impact-capable bit when extra force is needed. Construction and metalwork: Drive high-strength fasteners into metal or hard substrates with consistent accuracy and reduced bit damage. Quick tips Match the bit type to the screw head for best fit and to minimize wear. For impact drivers, use the impact-rated bit to ensure durability and safety. Securely mount the hex bit in the chuck or holder to simplify assembly and disassembly. Materials and function summary Material: Wear-resistant, alloyed steel with high hardness. Bit types: Slip-resistant cross (Phillips), hex (six-sided) screwdriver, and impact-resistant drill/screwdriver bit. Primary function: Efficient, precise fastening and removal of high-strength screws across hand and power tools.
