Proto, J1222SPL, Combination Wrench, 11/16 in, 12-Spline, Full Polish, 10.3 in Length

The Proto Combination Wrench is engineered for versatility and effectiveness in demanding environments, showcasing an 11/16-inch sizing designed to accommodate various fasteners. With a robust 12-spline drive type, it enhances grip and precision, significantly minimizing the risk of foreign object debris (FOD) while tightening high-strength bolts to ensure excellent torque loads. Its full polish finish not only provides an attractive, easy-to-clean surface but also offers corrosion resistance, making it suitable for use in both military and commercial aircraft as well as in heavy machinery applications where vibration is a concern. Additionally, the anti-slip design of the open end allows for greater control, helping to prevent rounding on standard fasteners and effectively handling those with damaged corners.

Features

• Spline helps reduce foreign object debris (FOD) by having a precise fit between the fastening tool and its fastener
• Spline fasteners help tighten high strength bolts to high torque loads
• 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
• 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
