Proto J1228MBASD Combination Wrench 28 Mm 15 Degree Offset

Product Description

The PROTO J1228MBASD is a 28 mm combination wrench built for professional trade use in mechanical, industrial, and maintenance applications. It features a 12-point box end with a 15-degree offset angle and a straight open end, giving technicians the versatility to drive fasteners in tight clearance situations or open-face access points. The overall length is 14-7/8 inches, providing solid torque leverage without adding unnecessary bulk. Constructed from corrosion-resistant steel, this wrench is built to hold up in demanding shop and field environments. It meets ASME B107.100-2010 standards and is tether capable for use in elevated or restricted work areas where dropped tools are a safety concern.

The J1228MBASD is suited for heavy equipment maintenance, fleet service, industrial assembly, and facility repair work where metric fasteners in the larger size range are common. Its tether-capable design makes it appropriate for working at height under fall-protection tool programs. The 15-degree offset box end helps clear obstructions around bolt heads and nuts in confined spaces. Mechanics, millwrights, and maintenance technicians working in manufacturing, construction, and utility environments will find this wrench a practical addition to a metric hand tool set.

Installation Notes

This wrench is installed and used by mechanics, millwrights, and maintenance technicians working on metric-fastened equipment. Before performing any mechanical service, de-energize, lock out, and tag out equipment per applicable LOTO procedures. When using this tool at height or in restricted areas, attach a tether to a rated anchor point before beginning work. Do not use extensions or cheater bars on this wrench, as this can exceed safe torque limits and damage fasteners or the tool.
