Proto J3164 Open End Wrench 2 Inch Double End

Product Description

The PROTO J3164 is a double-ended open end wrench sized at 2 inches, built for professional trade use in mechanical, HVAC, plumbing, and industrial maintenance applications. The wrench is machined from steel with a chrome-plated finish that resists corrosion and makes cleanup straightforward. Head angles are set at 15 degrees and 60 degrees, giving the technician two offset options in a single tool. At 4.19 pounds and approximately 20.7 inches in length, it is a heavy-duty hand tool suited for high-torque fastener work on large fittings and hardware.

This wrench is used wherever a 2-inch open end fitting is required, including large pipe fittings, mechanical equipment fasteners, and industrial machinery connections. The dual head angle design is especially useful in confined spaces where a straight approach is not possible. Residential and commercial HVAC technicians, plumbers, pipefitters, and general maintenance mechanics are the primary users. It meets GGG-W-636E federal specifications, confirming dimensional and performance standards for professional-grade hand tools.

Installation Notes

This wrench is a hand tool and does not require installation. Technicians should confirm the fastener size matches the 2-inch jaw opening before applying torque. When working on pressurized systems, depressurize and isolate the system before using any hand tool on fittings. Keep the chrome-plated surface clean and dry to maintain finish integrity.
