- 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 are also used in automotive and industrial areas where high performance torque needs to be achieved
- 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
