Proto, J1210SPL, Combination Wrench, 5/16 in, 12-Spline, Full Polish, 5.5 in

Engineered for superior performance, the Proto combination wrench seamlessly combines functionality and durability. This 5/16-inch tool features a 12-spline design, specifically crafted to service high tensile strength fasteners commonly found in military and commercial aircraft as well as heavy machinery applications. Its full polish finish not only enhances corrosion resistance but also ensures an easy-to-clean surface, making maintenance a breeze. With a unique anti-slip design and precise fit, this wrench aids in reducing the force needed to turn fasteners and prevents rounding, providing reliability even on damaged corners. The innovative spline design enhances the tightening of high strength bolts to achieve optimal torque loads, meaning that whether you're working in automotive or industrial settings, this tool is up to the task.

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