• Size - Phillips head size: PH1 (#1); total length: 100mm / 4"; hex shank size: 1/4"(6.35mm); hardness: HRC60-61 (The recognized stable hardness is around HRC60.). Screws for large household appliances are mainly PH2/PH3, those for small household appliances are mainly PH1.
• Material - The impact screwdriver bits are made of specially heat-treated S2 steel, which offers high strength and hardness (HRC60-61). They are durable, anti-bending, and feature a black phosphate finish for enhanced corrosion resistance, adhesion, and surface hardness.
• Features - Designed with magnetism can stably absorb the screws vertically or tilted and easily fix the screws, especially in a small space, which can make it more convenient to complete the work. Precision CNC machined cross head, precise appearance, reduces head wear during high-intensity tightening operations.
• Applications - Phillips tip screwdriver bit can easily screw into wood, metal and other materials. Screws can be tightened precisely without damaging the screws and screwdriver heads. 1/4" hex shank driver bits can be used with electric screwdrivers, manual screwdrivers, electric drills, etc. for electrical work, mechanical repair work, and furniture installation.
• Notes - Before operation, make sure the screwdriver bit is firmly inserted into the power tool chuck. Avoid excessive force when tightening the screw to prevent the bit from being damaged or slipping out. Adjust power tool speed and torque settings according to the material being processed.
