Stanley FATMAX FMMT13065-0 open end wrench

The STANLEY FATMAX FMMT13065-0 open end wrench is a single-piece 8x9 mm stainless-finish hand tool forged from chrome-vanadium steel. With a length of 200 mm and a compact weight of 32 g, it combines corrosion resistance and structural strength for routine fastening and loosening tasks. The double open-end design provides two sizes in one tool and the 15° offset increases clearance and access in confined spaces. A pocket holder feature supports convenient transport and on-site accessibility.

Advantages

The chrome-vanadium construction and satin chrome surface improve durability and resist corrosion during regular use. The anti-slip profile enhances contact with fasteners to reduce rounding and slipping. Having two open ends in a single wrench reduces the number of tools required for mixed-size fasteners, while the 15° offset improves working angle and reach in restricted areas. The wrench’s slim profile and pocket holder aid portability and storage.

Suitable for

• General mechanical assembly and maintenance
• Automotive and bicycle repairs where 8 mm and 9 mm fasteners are common
• Installation tasks in tight spaces or recessed fasteners

How to use

Select the correct end (8 mm or 9 mm) and place the wrench fully onto the fastener to ensure full tooth engagement. Apply steady force in the required direction; use the 15° offset to avoid knuckle contact with nearby surfaces and to gain clearance in confined spaces. When switching between sizes, rotate the wrench to use the alternate open end. Store the wrench in a pocket or tool pouch using the integrated pocket holder to keep it accessible during work.

Usage recommendations

Inspect the wrench before use for signs of wear or deformation. Do not use the wrench on fasteners that require higher torque than its size and construction allow; consider a larger or different type of wrench if excessive force is needed. Clean and lightly oil after use to maintain the satin chrome finish and reduce corrosion over time.
