Proto J1275M Combination Wrench 75 Mm 34 Inch

Product Description

The PROTO J1275M is a heavy-duty combination wrench designed for large-fastener work in industrial, mechanical, and maintenance environments. It features a 75 mm open and box-end head with a 15-degree offset angle on the box end, giving technicians the knuckle clearance needed in tight spaces. The wrench measures 34 inches overall length and is constructed of steel with corrosion-resistant properties. At 19.25 pounds, this is a full-size industrial tool built for high-torque applications. The tether-capable design supports use in elevated or safety-critical work environments where dropped-tool protocols are required.

This wrench is suited for heavy industrial maintenance, large machinery service, structural assembly, and applications where fasteners exceed the size range of standard combination wrenches. The 34-inch length provides substantial leverage for breaking loose large or corroded fasteners. Its straight handle and 15-degree offset make it practical for both flat-surface and recessed-fastener scenarios. Licensed mechanics, millwrights, pipefitters, and industrial maintenance technicians are the primary users of this tool class.

Key Features

• 75 mm head size accommodates large industrial fasteners
• 15-degree box-end offset angle improves clearance in confined spaces
• 34-inch overall length delivers high leverage for heavy-torque applications
• 12-point box end for multiple engagement positions on the fastener
• Tether-capable design supports dropped-object prevention programs
• Corrosion-resistant steel construction meets ASME B107.100-2010 standards

Compatibility

Designed for use with 75 mm hex fasteners in industrial maintenance and heavy equipment service applications where large-format combination wrenches are required.

Installation Notes

This wrench is a hand tool requiring no installation, but safe use practices apply. Always confirm the wrench head is fully seated on the fastener before applying force to prevent rounding. When working at height or in safety-critical environments, attach an approved tether to the tether-capable point before use. Inspect the tool for cracks or deformation before each use and remove from service if damage is found.
