The Proto Industrial 6-Point Impact Socket is engineered for the toughest professional applications, featuring a 3/4-inch drive and 40mm opening. The 6-point design maximizes contact with fastener flats, reducing the risk of rounding and delivering superior torque transfer in demanding industrial and MRO environments.
Built to Proto's industrial-grade standards, this socket is ideal for heavy-duty fastening tasks on machinery, equipment maintenance, and assembly lines where reliability and durability are critical. The 3/4-inch drive accommodates high-torque impact wrenches for efficient, secure fastening.
