Proto, J5220SPL, Spline Socket, 3/8 in Drive; 5/8 in Size; Metal, Full Polish Chrome

Engineered for precision and strength, the Proto 3/8 inch drive spline socket is a vital tool for servicing high tensile strength fasteners commonly found in military, commercial aircraft, and heavy machinery. Its unique spline design enables this socket to provide twice the torque of traditional 12-point wrenches, making it ideal for high-performance tasks where torque loads need careful management. The full polish chrome finish not only adds to its durability but also helps to prevent foreign object debris (FOD) by ensuring a snug fit between the tool and the fastener. This versatile tool is essential for automotive and industrial applications, capable of effectively tightening high strength bolts while also accommodating those with damaged corners.

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.
• Spline sockets 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 to help prevent fastener rounding. They also turn fasteners with damaged corners.
• Spline sockets on spline fasteners help deliver twice the torque of 12 point wrenches on double box fasteners, and more torque than hex wrenches on hex fasteners.
• Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener.
