Proto J1228M-T500 Combination Wrench 28 Mm

Product Description

The PROTO J1228M-T500 is a 28 mm combination wrench built for professional mechanics, industrial maintenance technicians, and trade professionals who require a durable, precision-made hand tool. The wrench features a 15-degree offset head angle on a straight handle, allowing clearance over fasteners in confined work areas. Constructed from steel with a polished finish, it measures 14-7/8 inches overall length and weighs 1.33 pounds. The tether-capable design supports use in elevated work environments or any application where tool retention is required for safety compliance. It meets ASME B107.100-2010 standards and carries a lifetime warranty.

This wrench is suited for heavy equipment maintenance, industrial assembly, and mechanical service work in both shop and field environments. The 28 mm head size fits metric fasteners common on commercial vehicles, heavy machinery, and industrial equipment. The 15-degree offset provides knuckle clearance and improved torque angle in tight access points. It is appropriate for any trade professional requiring a reliable, full-size metric combination wrench for regular service work.

Installation Notes

This wrench is intended for use by qualified mechanics and maintenance technicians. Always confirm fastener size before applying torque to avoid rounding. When used in elevated or overhead environments, attach the tether anchor point to an appropriate lanyard or tool tethering system per applicable worksite fall-protection protocols. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found.
