Proto, J1216SPL, Combination Wrench, 1/2 in, 12-Spline, 7.9 in Length, Full Polish Finish

Crafted with precision and designed for performance, this combination wrench features a 12-spline drive type, allowing it to effectively service high tensile strength fasteners. The tool’s anti-slip design ensures a secure grip on open ends, making it ideal for tackling high torque loads often required in military and commercial aircraft applications, as well as heavy machinery. Its full polish finish not only boasts corrosion resistance but also facilitates an easy-to-clean surface, ensuring longevity and reliability. The unique spline design reduces the force needed to turn standard fasteners and enhances the ability to handle those with damaged corners, positioning it as a vital tool for automotive and industrial mechanics alike.

Features

• Anti-Slip Design (ASD) open end
• Full polish finish provides corrosion resistance and an easy to clean surface
• Spline fasteners help tighten high strength bolts to high torque loads
• 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
• 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
