Spline Sockets, #5 Spline, 2 in, 6 Points

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 | 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
