3/8 in Drive, 5/8" Spline SAE Socket, 12 Points

Proto Spline tools are designed for high-tensile strength fasteners in harsh environments like military and commercial aircraft, heavy machinery, and industrial applications. They help achieve high-performance torque and tighten high-strength bolts to high torque loads. Spline sockets reduce the force needed to turn standard fasteners, prevent fastener rounding, and turn fasteners with damaged corners. This results in increased torque and reduced foreign object debris (FOD). Suitable for use in automotive, aerospace, and industrial areas, Proto Spline tools deliver twice the torque of 12-point wrenches on double box fasteners and more torque than hex wrenches on hex fasteners.

Top product features:

  • Spline sockets help tighten high strength bolts to high torque loads.
  • Spline sockets help 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.
  • Spline sockets help turn fasteners with damaged corners.

Top product applications:

  • Military and commercial aircraft
  • Heavy machinery applications where vibration is prevalent
  • Automotive areas where high performance torque needs to be achieved

Proto® Spline tools are designed to service high tensile strength fasteners used widely on military and commercial aircraft and in heavy machinery applications where vibration is prevalent. They are also used in automotive and industrial
areas where high performance torque needs to be achieved
Spline sockets help tighten high strength bolts to high torque loads. They help 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. They also turn fasteners with damaged corners

Additional Features:

  • - Spline sockets on spline fasteners help deliver twice the torque of 12 point wrenches on double box fasteners, and more torque than hex wrenches on hex fasteners
  • - Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
