Gearwrench 85913 13mm 12 Point Double End Box Wrench

Product Description

The GEARWRENCH 85913 is a double-end box wrench built for professional tradespeople who need reliable fastener engagement in tight quarters. Sized at 13 mm with a 12-point configuration on each end, it provides multiple contact angles and reduces the arc needed to reposition the wrench. The head carries a 0-degree offset angle, keeping the tool flat against the work surface for low-clearance applications. Constructed from chromium-vanadium steel with a polished finish, the 85913 resists corrosion and handles the torque demands of daily mechanical and maintenance work. The ratcheting action allows forward motion without removing and reseating the wrench.

This wrench is suited for automotive, HVAC, plumbing, and general mechanical maintenance work where a box-end profile is required. The 12-point design engages standard hex fasteners and works in situations where a hex key or open-end wrench lacks the grip needed for stubborn or rusted hardware. The flat 0-degree head angle makes it practical on panels, flanges, and bracket hardware where raised-profile wrenches create clearance problems. The double-end configuration provides two working ends in a single tool, reducing the number of hand tools a technician needs on the job.

Key Features

• 12-point box end provides multiple engagement positions for tight-swing applications
• Ratcheting mechanism allows continuous drive without repositioning the wrench
• 0-degree head offset angle suits flat-surface and low-clearance fastener work
• Chromium-vanadium steel construction handles high torque without deforming
• Polished corrosion-resistant finish extends service life in field conditions
• Meets ANSI and ASME specifications for hand tool performance

Compatibility

Designed as a standard 13 mm double-end box wrench suitable for metric fasteners across automotive, HVAC, plumbing, and general mechanical maintenance applications.

Installation Notes

This wrench is installed and operated by mechanics, HVAC technicians, plumbers, and general maintenance trades. Before using on any system, de-energize electrical components and relieve pressure from pressurized lines per applicable codes. Use the correct size wrench to avoid rounding fastener heads. Do not extend the handle with a cheater bar, as this can exceed the rated torque capacity of the tool.
