Material - The 4-point drive socket is made of high-hardness 40CR stainless steel, which has excellent impact and wear resistance, making it resistant to deformation and damage, and suitable for use in high-torque environments. The polished blackened surface helps prevent rust and corrosion, extending the tool's lifespan. FEATURES - The impact socket's port features a 4-point square design, which better fits square-head screws and nuts, providing a stronger grip during use, preventing fasteners from rounding up, and reducing slippage. The anti-drop hole design on the base helps secure the socket to the tongue of your air wrench or driver, preventing pins from falling out, ensuring safe use. Application - The specifications of the square socket are clearly engraved on the surface. This allows you to quickly switch between different socket sizes during work, improving work efficiency. Square wheel sockets are widely used for removing and tightening square-head bolts and nuts on various structural fasteners. Suitable for auto repair, DIY crafts, construction, and machine maintenance. CAUTION - Ensure the selected socket size matches the head of the screw or nut to prevent slippage or damage due to mismatched sizes. Use a professional wrench or torque wrench to match the socket to avoid affecting torque transmission or damaging the socket. When using a socket tool to tighten or loosen screws, apply force evenly and appropriately to avoid excessive force that may damage the socket or threads.
