Proto J1218MESB Combination Wrench 18 Mm 12-point

Product Description

The PROTO J1218MESB is a 12-point combination wrench designed for professional-grade fastener work in industrial, mechanical, and maintenance applications. Built from corrosion-resistant steel with a 15-degree offset head, it provides clearance over obstructions while maintaining positive engagement on 18 mm fasteners. The open end and box end are combined in a single tool, giving technicians two drive options without a tool change. At 5.25 inches overall length and 0.29 pounds, it is sized for tight-access work. The tether-capable design supports use in elevated or confined environments where dropped tools are a safety concern. Meets ASME B107.100-2010 standards.

This wrench is suited for HVAC equipment assembly, mechanical contractors, industrial maintenance crews, and utility technicians working on machinery, piping supports, and structural fasteners. The 18 mm head size addresses metric hardware commonly found on commercial equipment, imported machinery, and modern HVAC and refrigeration systems. The straight handle and offset box end make it a reliable daily-carry tool for technicians working from ladders, elevated platforms, or inside confined equipment panels where dropped-tool prevention is required by site safety protocols.

• Tether-capable design supports dropped-object prevention programs on elevated work sites
• Corrosion-resistant steel construction for durability in field and shop environments
• Meets ASME B107.100-2010 standard for combination wrenches

Compatibility

Designed as an OEM-style hand tool replacement or addition for professional tool kits requiring an 18 mm metric combination wrench with tether capability.

Installation Notes

This wrench is installed and used by licensed mechanics, HVAC technicians, plumbers, and industrial maintenance professionals. Before applying torque to system fasteners, confirm the system is de-energized or depressurized as required by applicable safety procedures. Use with an appropriate tether anchor point when working at height in compliance with site dropped-object prevention requirements. Do not use extensions or pipe over the handle to increase leverage beyond the tool's rated design.
