Gearwrench 81842 Combination Wrench 46 Mm 12-point

Product Description

The GEARWRENCH 81842 is a large-format combination wrench built for heavy-duty fastener work on industrial, mechanical, and trade job sites. At 46 mm head size and 25.551 inches overall length, this wrench delivers the reach and leverage needed for large-diameter fasteners. The 12-point offset box end provides multiple engagement positions in confined areas, while the open end handles quick flat-to-flat turns. Constructed from steel with a satin finish, the 81842 meets ANSI and ASME standards and carries a limited lifetime warranty. At 5.15 pounds, it is a substantial tool suited for high-torque applications.

This wrench is used in heavy equipment maintenance, industrial piping, structural steel work, and large-engine service where oversized fasteners are common. The 46 mm size falls outside standard automotive ranges, making it a go-to for fleet mechanics, millwrights, and industrial maintenance technicians working on hydraulic systems, compressors, pumps, and similar equipment. The extended 25.551-inch length provides mechanical advantage without needing a cheater bar extension.

Installation Notes

This tool is typically used by journeymen mechanics, millwrights, and industrial maintenance technicians. Always confirm the fastener size before applying torque to avoid rounding. On corrosion-seized fasteners, apply penetrating oil before use to reduce the risk of damaging the fastener or the wrench. Do not use pipe extensions to increase leverage beyond the tool's rated design.
