The Force ½″ Drive 12‑Point Bihex Impact Socket, 22 mm is a rugged, high-quality tool designed for heavy-duty use: Drive & Points: ½″ square drive with a 12-point (bihex) hex opening—ideal for fitting onto fasteners quickly, especially in tight or hard-to-reach spots Size: 22 mm across flats. Material & Finish: Constructed from premium Chrome‑Molybdenum (Cr‑Mo) steel with a black phosphate (or matte) finish—built for strength, impact resistance, and corrosion protection Use Case: Specifically engineered for impact wrenches—stronger and safer than standard chrome vanadium sockets when dealing with high torque Benefits: 12‑point design allows for faster engagement, requiring less rotation to seat on the fastener. Robust build handles repeated high-impact use without cracking or rounding. Versatile for both automotive and industrial applications.
