  • Item Features
  • Application
  • Standards
  • 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
  • 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
  • Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
  • They are also used in automotive and industrial areas where high performance torque needs to be achieved
