3/8 in Drive, 5/8 in SAE, Socket, 12 Points, Chrome, 5/8 in

Proto Spline sockets are designed to service high tensile strength fasteners on military and commercial aircraft, heavy machinery, and in automotive and industrial areas where high performance torque is required. They help tighten high strength bolts to high torque loads, lower the force required to turn standard fasteners, and turn fasteners with damaged corners. Spline sockets deliver twice the torque of 12-point wrenches on double box fasteners and more torque than hex wrenches on hex fasteners. They also reduce foreign object debris (FOD) and provide a precise fit between the fastening tool and its fastener.

Top product features:

  • Helps lower the force required to turn standard fasteners by allowing the torque load to be moved away from the corners to help prevent fastener rounding.
  • Helps turn fasteners with damaged corners.
  • Delivers twice the torque of 12 point wrenches on double box fasteners, and more torque than hex wrenches on hex fasteners.

Top product applications:

  • Military aircraft maintenance
  • Heavy machinery repair
  • Automotive repair
