Proto 3/8" Drive Impact Socket 9/16" - 8 Point J7218S-SBD

Proto's 3/8 in. Drive 8-Point Impact Socket is a professional-grade tool designed for specialized square fasteners, offering superior durability and engagement. This Proto® 8-Point Impact Socket features the advanced TorquePlus™ design, which ensures quick and easy engagement on the fastener flats—not the corners—virtually eliminating fastener rounding and minimizing slippage. This makes it ideal for safely turning stubborn, damaged, or rusted fasteners while extending their life. Made from high-strength steel, its construction allows access to fasteners in recesses, and the drive end includes a chamfer and four detents for quick, positive engagement. The socket size is clearly stamped for easy reference, and a side locking hole provides secure retention to the impact tool.
