Stanley FATMAX FMMT13062-0 open end wrench

Flat open-end wrench by STANLEY, size 6x7 mm with anti-slip finish, designed for tightening and loosening parallel-sided hex fasteners in confined or hard-to-reach spaces. The compact double-ended design provides two metric sizes in one tool, reducing the need to carry multiple wrenches. Durable construction suits general maintenance, bicycle and household repairs, and light mechanical work.

Advantages

The anti-slip finish improves grip on the wrench and reduces the chance of slippage during use, while the slim flat profile allows access into tight gaps where bulkier tools cannot reach. Being double-ended, the tool offers two commonly used metric sizes in a single piece, saving space in a toolbox. Hardened metal construction ensures resistance to wear and provides consistent leverage for small fasteners.

Suitable for

• Tightening and loosening 6 mm and 7 mm hex nuts and bolts in confined spaces
• Bicycle maintenance and adjustments on small components
• Household repairs where compact hand tools are needed
• Light mechanical and assembly tasks requiring precise small wrenches

Key specifications

• Sizes: 6 mm and 7 mm (double-ended)
• Tool type: Flat open-end wrench
• Finish: Anti-slip surface treatment for improved grip
• Profile: Slim, flat design for access in narrow spaces
• Material: Hardened metal for wear resistance and durability
• Length: Compact size suitable for toolbox and on-the-go use

How to use

Select the correct end (6 mm or 7 mm) that matches the nut or bolt head. Place the flat open-end jaws fully onto the fastener to ensure an even load on the flats, then apply steady turning force in the required direction. For confined spaces, position the slim profile of the wrench into the gap and operate with controlled movements to avoid rounding the fastener. After use, wipe off dirt or grease and store the wrench in a dry toolbox to maintain the anti-slip finish and prevent corrosion.

Usage recommendations

Use the wrench only on parallel-sided hex fasteners of the matching sizes; avoid using the tool as a hammer, pry bar, or on rounded/damaged fasteners. For higher torque requirements, use an appropriately sized combination or box-end wrench to reduce the risk of fastener damage. Regularly inspect the open ends for wear and maintain cleanliness to preserve the anti-slip surface.
