Features

• 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
• Anti-Slip Design (ASD) open end
• Full polish finish provides corrosion resistance and an easy to clean surface
• Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
• 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
