The PROTO J3045 is a double-ended open end wrench built for professional tradespeople who need a reliable, dual-size hand tool for fastener work in HVAC, plumbing, electrical, and mechanical service applications. Sized at 15/16 inch by 1 inch, it covers two common fastener sizes in a single tool. The head is machined at a 15-degree angle to improve access in tight or obstructed spaces. Constructed from steel with a satin finish, the J3045 is designed for long-term service under daily job-site conditions. It meets ASME B107.6 and GGG-W-636E standards and carries a lifetime warranty from PROTO.
The J3045 suits residential and commercial service work across multiple trades. It is a practical choice for HVAC technicians torquing fittings and hardware, plumbers working on supply and equipment connections, and electricians or mechanics handling structural fasteners. The 15-degree angled head makes it easier to drive fasteners in recessed or confined areas where a straight-head wrench cannot get a full swing. The dual open-end configuration reduces the number of wrenches a technician needs to carry for adjacent fastener sizes.
Designed as a standard open end wrench for 15/16 inch and 1 inch fasteners across general mechanical, HVAC, plumbing, and electrical service applications.
This wrench is a hand tool requiring no installation; however, always select the correct jaw size before applying torque to avoid rounding fastener heads. Power down or de-energize equipment before loosening or tightening fasteners on live mechanical or electrical systems. Follow applicable codes and equipment manufacturer torque guidelines when fastener specifications are provided.
