Proto J1227MBASD Combination Wrench 27 Mm 15 Degree Offset

Product Description

The PROTO J1227MBASD is a 27 mm combination wrench designed for heavy-duty fastener work in professional trade environments. It features a 15-degree offset head that improves knuckle clearance and access in tight spaces. The 12-point box end accepts both standard and metric hex fasteners and allows repositioning in confined areas. Built from corrosion-resistant steel, it measures 14-7/8 inches overall and weighs 1.42 pounds. The wrench is tether capable, making it suited for elevated work sites where dropped-tool protocols are required. It meets ASME B107.100-2010 standards and carries a lifetime warranty from the manufacturer.

This wrench is used by mechanics, millwrights, pipefitters, and maintenance technicians working on large fasteners in industrial, commercial, and utility settings. The 27 mm size is common on heavy equipment, flanged pipe connections, structural bolting, and machinery. The straight handle and offset head geometry make it practical for both torque-intensive pulls and controlled finishing work. The tether-capable design satisfies tool-drop prevention requirements on elevated platforms, scaffolding, and aerial work.

Installation Notes

This wrench is intended for use by qualified mechanics, pipefitters, millwrights, or maintenance technicians. Ensure the correct metric size is matched to the fastener before applying torque to avoid rounding. When using on elevated surfaces or scaffolding, attach a tether lanyard to the tether point before beginning work in accordance with your site dropped-object prevention program. Inspect the wrench for cracks or deformation before each use and remove from service if any damage is found.
