Proto, J1212SPL, Combination Wrench, 3/8 in, 12-Spline, Full Polish, 5.9 in Length

Crafted by Proto, this combination wrench is an essential tool for anyone working with high tensile strength fasteners used in demanding environments such as military and commercial aircraft, as well as heavy machinery. With its innovative 12-spline design, this wrench excels in delivering the high torque necessary for tightening bolts while minimizing the risk of rounding the corners of fasteners, even those with damage. The full polish finish not only enhances its aesthetic appeal but also provides superior corrosion resistance and a surface that is easy to clean, making it ideal for both automotive and industrial applications. Additionally, the anti-slip design ensures a secure grip, allowing for reliable performance in situations where vibration is prevalent. At 5.9 inches in length, this reliable tool combines efficiency with durability, making it a standout choice for professionals and DIY enthusiasts alike.

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
