Proto J1255M Combination Wrench 55 Mm 15 Degree Offset

Product Description

The PROTO J1255M is a heavy-duty combination wrench built for professional technicians working on large fasteners in industrial, mechanical, and facilities maintenance applications. It features a 55 mm head size with a 15-degree offset angle and a 12-point box end, giving users better torque access in tight or obstructed workspaces. The wrench measures 28.75 inches overall and is constructed from steel with a corrosion-resistant satin finish. It is tether capable, making it suitable for work at height or in controlled-tool environments. This wrench meets ASME B107.100-2010 standards and carries a limited lifetime warranty.

The J1255M is designed for industrial and heavy mechanical service work where large-diameter fasteners are common. Typical applications include heavy equipment maintenance, structural assembly, pipeline work, and industrial machinery service. The large 55 mm head size places this wrench in the range used by millwrights, heavy-equipment mechanics, pipefitters, and facilities maintenance professionals. Its straight handle and offset box end suit both overhead and bench-level work on large bolted connections.

Installation Notes

This wrench is a hand tool intended for use by qualified mechanics, millwrights, pipefitters, and maintenance technicians. Inspect the wrench for cracks or deformation before each use. When using in elevated work areas, attach the tether point to an approved tool lanyard in accordance with applicable fall protection and tool control requirements. Do not use cheater bars or pipe extensions to increase leverage beyond the design capacity of the tool.
