Proto J1218MH-T500 Combination Wrench 18 Mm Tether Capable

Product Description

The PROTO J1218MH-T500 is a combination wrench built for professional tradespeople who need a reliable, corrosion-resistant hand tool in demanding service environments. It features an 18 mm head size with a 15-degree offset angle and a 6-point box end, giving technicians better torque transfer and reduced fastener rounding compared to 12-point designs. The overall length is 10.5 inches, and the chrome finish provides corrosion resistance for long service life. At 0.5 pounds, it is light enough for overhead work and confined spaces. The tether-capable design makes it appropriate for work at height or in environments where dropped tools present a safety hazard.

This wrench is suited for HVAC, mechanical, electrical, and general maintenance applications where metric fasteners are standard. The straight handle and 15-degree head offset allow clearance in tight spaces without sacrificing leverage. It is an appropriate choice for industrial facilities, commercial job sites, and service vehicles where tool accountability and corrosion resistance are required. Tether attachment points allow use with standard fall-arrest tool lanyards.

Installation Notes

This tool is installed and used by licensed trades and maintenance professionals across commercial and industrial settings. Before use at height, attach an approved tool lanyard to the tether point per applicable fall protection requirements. Inspect the wrench for cracks or deformation before each use and do not use it as a hammer or pry bar. When working on energized or pressurized systems, follow applicable lockout/tagout procedures before applying the wrench to any fastener.
