The Proto J Series 17mm impact socket features a 3/8-inch drive and 6-point design built to withstand high-torque impacts. Manufactured from heat-treated steel for strength and durability, this socket maintains its position even when fully extended, making it ideal for demanding industrial and MRO applications.
Engineered for hard-to-reach fasteners, the Proto J Series slim profile accesses recessed or partially covered fasteners that standard sockets cannot reach. A reliable choice for professional mechanics and tradespeople requiring dependable impact-rated tooling.
