Gearwrench 86741 Combination Wrench 5/16 Inch 12-point

Product Description

The GEARWRENCH 86741 is a 5/16 inch combination wrench built for professional fastener work across HVAC, plumbing, electrical, and general mechanical applications. It pairs an open-end jaw with a 12-point box-end ring in a single alloy steel body, finished in polished chrome for corrosion resistance and easy cleaning. At 8.2 inches in total length, it provides enough leverage for standard 5/16 inch fasteners without excess bulk. Licensed trades and service technicians reach for this wrench when working on equipment panels, bracket hardware, and pipe fittings where a dedicated combination wrench is faster than an adjustable.

This wrench is suited for residential and light commercial service work where 5/16 inch fasteners appear on equipment enclosures, electrical panels, HVAC units, and plumbing fixtures. The 12-point box end engages fasteners at 30-degree intervals, making it usable in tight quarters with limited swing arc. It is a single-piece hand tool requiring no setup, calibration, or accessories. The compact head profile fits into recessed fastener locations common in equipment service panels.

Key Features

• 12-point box end allows engagement every 30 degrees for use in confined spaces
• Alloy steel construction provides strength and durability under hand-torque loads
• Polished chrome finish resists corrosion and simplifies cleaning of grease and debris
• 5/16 inch head size fits standard SAE fasteners common in HVAC and mechanical assemblies
• Single-piece combination design eliminates need for separate open-end and box-end wrenches

Compatibility

Designed as a standard SAE combination wrench for use with 5/16 inch fasteners across residential and light commercial mechanical, HVAC, plumbing, and electrical service applications.

Installation Notes

This is a hand tool requiring no installation. Always de-energize electrical equipment and shut off gas or water supply before using hand tools on service connections. Select the correct wrench size to avoid rounding fastener heads. Do not use a cheater bar or extension on a standard combination wrench to increase leverage beyond its rated hand-torque capacity.
