Proto J1270-14A Combination Wrench 7/16 Inch Satin Finish

Product Description

The PROTO J1270-14A is a combination wrench with a 7/16 inch head size and a 15-degree offset angle. It features one open end and one box end on a straight handle, giving technicians two engagement options in a single tool. Built from steel with a satin finish, this wrench is sized for tight fastener work in mechanical, HVAC, plumbing, and electrical service applications. The overall length of 6.88 inches keeps it maneuverable in confined spaces. At 0.24 pounds, it is lightweight enough for extended use without fatigue.

Installation Notes

This wrench is a hand tool used by HVAC technicians, plumbers, electricians, and mechanical contractors. No power source is required. Ensure the correct head size is matched to the fastener before applying torque to avoid rounding. Inspect the wrench for cracks or deformation before each use and do not use as a striking tool or extend with a cheater bar.
