Proto, J1220SPL, Combination Wrench, 5/8 in; 12-Spline, Full Polish, 9.6 in

Crafted for both military and commercial applications, the Proto combination wrench is designed to provide reliable service on high tensile strength fasteners, making it ideal for use in heavy machinery as well as automotive and industrial environments. The 5/8-inch size and 12-spline drive type enhance its functionality, allowing for effective tightening of high strength bolts, while also protecting against fastener rounding caused by traditional tools. Its innovative anti-slip design allows for handling damaged corners, and the full polish finish not only offers corrosion resistance but also ensures easy cleaning, contributing to its durability in demanding settings. This tool stands out for its ability to reduce foreign object debris, ensuring a precise and efficient fit between the wrench and fastener, thus elevating performance even in challenging conditions.

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 fasteners 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, 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 Anti-Slip Design (ASD) open end
