Proto, J1118SPL, Wrench, 1/4 in x 5/16 in, Double Box, Spline, 7.3 in

Designed for professionals dealing with high tensile strength fasteners, this wrench is an essential tool for both military and commercial aircraft as well as heavy machinery applications. The double box design and spline drive style not only help to minimize the force required to turn standard fasteners but also allow for effective engagement with fasteners that may have damaged corners, thus preventing rounding and potential damage. With a full polish finish, the tool provides exceptional corrosion resistance and is easy to clean, making it highly functional in environments where vibration is prevalent. This 7.3-inch wrench is tailored to meet the demanding torque requirements commonly found in automotive and industrial settings, ensuring reliable performance and longevity.

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
• 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
• Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
• Full polish finish provides corrosion resistance and an easy to clean surface
• Spline fasteners help tighten high strength bolts to high torque loads
