Proto J3035B Open End Wrench 11/16 X 3/4 in Double End

Product Description

The PROTO J3035B is a double-ended open end wrench designed for professional tradespeople who need reliable, precise fastener access in tight spaces. Built from steel with a black finish, this wrench features a 15-degree head angle on both ends to improve swing arc clearance in confined work areas. The two jaw sizes — 11/16 inches and 3/4 inches — cover two of the most common fastener sizes found in mechanical, HVAC, plumbing, and electrical work. At 0.47 pounds, it is lightweight enough for extended use without fatigue.

This wrench is suited for residential and commercial service work where a single tool must handle adjacent fastener sizes quickly. The double-ended configuration eliminates the need to carry two separate wrenches, making it a practical choice for service technicians working from a tool pouch or roll. The 15-degree offset head angle allows access to fasteners in recessed or obstructed locations, which is common in equipment panels, pipe flanges, and mechanical assemblies.

Installation Notes

This wrench is used by licensed HVAC technicians, plumbers, pipefitters, and electricians across a wide range of service tasks. No power-down or system isolation is required for the tool itself, but always follow proper lockout/tagout procedures when servicing energized or pressurized equipment. Ensure the correct jaw size is fully seated on the fastener before applying torque to prevent rounding.
