Spline Sockets, #5 Spline, 2 3/4 in, 6 Points

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
