Proto J3060 Open End Wrench 1-3/8 X 1-7/16 in Steel

Product Description

The PROTO J3060 is a double-ended open end wrench built for professional trade use in mechanical, HVAC, plumbing, and industrial service applications. It features a 15-degree head angle on both ends, allowing access in tight or obstructed fastener locations where a straight-head wrench cannot seat properly. The wrench is machined from steel with a satin finish that reduces glare and resists surface wear over repeated use. Jaw sizes are 1-3/8 inches on one end and 1-7/16 inches on the other, making it a practical two-in-one tool for large-fastener work. It meets ASME B107.6 and Federal Specification GGG-W-636E standards.

This wrench is well suited for service work involving large hex fasteners found on equipment mounts, pipe fittings, flanges, compressor hardware, and structural connections. The dual jaw sizes cover adjacent fastener dimensions commonly encountered when working on heavy mechanical systems, making it efficient for techs who need to minimize the number of tools carried to a job. Both residential and commercial service applications are appropriate given the jaw size range.

Installation Notes

This wrench is used by licensed HVAC technicians, plumbers, pipefitters, and general mechanical service professionals. Ensure the fastener is fully seated in the jaw before applying torque to prevent jaw spread or fastener rounding. Use in conjunction with appropriate personal protective equipment when working on pressurized or energized systems. Always de-energize, depressurize, or isolate equipment before breaking loose any fasteners.
