Proto J1250M Combination Wrench 50 Mm 28 Inches Steel

Product Description

The PROTO J1250M is a large-format combination wrench designed for heavy-duty fastener work on industrial, mechanical, and trade applications. The wrench features a 50 mm head size with a 15-degree offset angle and a 12-point configuration, giving technicians better access to fasteners in confined or obstructed areas. The overall length of 28 inches provides extended reach and substantial torque leverage. Constructed from steel with a satin finish, the J1250M is corrosion-resistant and built to meet ASME B107.100 standards. It is tether capable, making it suitable for use at height or in environments where dropped tools are a hazard.

This combination wrench is intended for professional use in industrial maintenance, heavy equipment service, pipeline work, structural assembly, and other applications requiring a large metric wrench. The 28-inch length and 50 mm opening make it well suited for large-diameter fasteners found on heavy machinery, flanges, and structural connections. The tether-capable design supports compliance with dropped-object prevention programs on job sites such as elevated platforms, towers, and industrial facilities.

Installation Notes

Installation and use should be performed by qualified mechanics or trade professionals familiar with large-format hand tools. Before applying torque, ensure the fastener and wrench head are fully engaged to prevent slippage or rounding. When using the tether point, attach an appropriately rated tool lanyard before working at height. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found.
