Proto, J4707DPL, Spline Socket, 1/4 in Drive, 2 in Length, 7/32 in Size, Full Polish Chrome

Engineered for high-performance applications, this spline socket from Proto is an essential tool for technicians working with high tensile strength fasteners, particularly in military, commercial aircraft, and heavy machinery sectors. With a drive size of 1/4 inch and a length of 2 inches, the 7/32 inch size securely accommodates fasteners, enabling superior torque capability—twice that of conventional 12 point wrenches on double box fasteners. The full polish chrome finish not only ensures durability but also provides a sleek, clean look. Designed with precision in mind, this socket helps minimize foreign object debris (FOD) and effectively tightens high-strength bolts while reducing the potential for fastener rounding, making it invaluable for professionals seeking reliability and high torque performance in demanding environments.

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 helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener.
• 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 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.
