Gearwrench 86021 Double Box End Wrench 21mm 12pt

Product Description

The GEARWRENCH 86021 is a double box end wrench designed for professional use in automotive, mechanical, and general maintenance applications. Built from steel with a chrome-plated finish, it features a 0-degree head offset angle and 12-point box ends on both sides. The ratcheting action allows fastener engagement without removing the wrench from the nut or bolt head, reducing repositioning time in tight spaces. At 18.9 inches in length and 1.425 pounds, it delivers solid leverage for 21 mm fasteners. This tool is intended for use by mechanics, technicians, and tradespeople working in shops or the field.

The 86021 suits residential, commercial, and industrial service environments where metric fasteners are standard. The double-end configuration and 12-point geometry make it well suited for hex fasteners in confined areas where swing arc is limited. The ratcheting box end design is particularly useful on equipment with repetitive fastener patterns, such as engine components, HVAC mechanical assemblies, or structural hardware requiring consistent torque application.

Key Features

• Ratcheting double box end design allows fastener driving without lifting the wrench
• 12-point geometry fits standard metric hex fasteners at 30-degree increments
• 0-degree head offset angle for flush access in flat work surfaces
• Chrome-plated steel construction with corrosion-resistant finish
• Meets ASME B107.100-2010 and ANSI specifications
• Limited lifetime warranty from the manufacturer

Compatibility

Designed as an OEM-style replacement or direct-use double box end wrench for 21 mm metric fasteners in automotive, mechanical, and general trade applications.

Installation Notes

This wrench is used by mechanics, HVAC technicians, and general tradespeople working with metric fastener systems. Ensure the fastener head is fully seated in the box end before applying force to avoid rounding. Inspect the tool for cracks or finish damage before each use. Store in a dry environment to preserve the chrome finish and corrosion resistance.
