Military, Commercial Aircraft, Automotive, Industrial and Heavy Machinery Applications
- 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 fasteners 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, helping prevent fastener rounding
- They also turn fasteners with damaged corners
- Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
- Full polish finish provides corrosion resistance and an easy-to-clean surface
