1/2 in Drive, 5/8" Spline SAE, Socket, 12 Points, Steel, Chrome, 5/8 in

Proto's 1/2 in Drive, 5/8in Spline SAE socket is designed to service high tensile strength fasteners in demanding applications such as military and commercial aircraft, heavy machinery, and automotive industries. Its spline design helps lower the force required to turn standard fasteners, prevent fastener rounding, and deliver twice the torque of 12-point wrenches on double box fasteners. Additionally, the precise fit reduces foreign object debris (FOD) and improves overall performance. Suitable for high-performance torque applications, this socket is a valuable tool for professionals who require reliable and efficient fastening solutions.

Top product features:

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

Top product applications:

  • Military and commercial aircraft
  • Heavy machinery applications where vibration is prevalent
  • Automotive and industrial 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
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
