1/4 in Drive, 3/8" Spline SAE Socket, 12 Points, Steel, Chrome, 3/8 in

Proto Spline tools are designed for high-tensile strength fasteners in military and commercial aircraft, heavy machinery, and automotive applications where high performance torque is required. Spline sockets help tighten high-strength bolts to high torque loads, reducing the force needed to turn standard fasteners and preventing fastener rounding. They also turn fasteners with damaged corners. With twice the torque of 12-point wrenches on double box fasteners and more torque than hex wrenches on hex fasteners, spline sockets deliver superior performance in demanding environments. They also minimize foreign object debris (FOD) with a precise fit between the fastening tool and fastener.

Top product features:

  • Spline design helps reduce foreign object debris (FOD) by providing a precise fit between the fastening tool and its fastener.
  • Spline sockets help tighten high strength bolts to high torque loads.
  • Spline sockets allow the torque load to be moved away from the corners, helping to prevent fastener rounding.

Top product applications:

  • Military and commercial aircraft
  • Heavy machinery applications
  • Automotive

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
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

Additional Features:

  • - Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
