Gearwrench 86743 Combination Wrench 3/8 Inch 12-point

Product Description

The GEARWRENCH 86743 is a 3/8 inch combination wrench built for professional tradespeople who need reliable hand tools on the job. It features an open end on one side and a box end on the other, with a 12-point box design that engages fasteners in tight spaces with minimal handle swing. Constructed from alloy steel with a polished chrome finish, the wrench resists corrosion and cleans up quickly between uses. This is a standard single-piece hand tool suited for mechanical, plumbing, electrical, and HVAC applications wherever 3/8 inch fasteners are encountered.

The GEARWRENCH 86743 suits residential and commercial service work across multiple trades. It is a practical addition to any tool kit where 3/8 inch hex fasteners appear on equipment panels, pipe fittings, electrical enclosures, or HVAC components. The 12-point box end allows use in confined areas where a full arc of rotation is not possible, making it useful for service techs working inside equipment cabinets or on overhead installations.
