Combination wrench AWTools AW39771, weight 70 g, size unspecified

AWTools AW39771 is a combination wrench crafted from chrome-vanadium (CrV) tool steel, designed to perform both open-end and ring-end turning of nuts and bolts. The single-piece, drop-forged construction is hardened and tempered for durability while a satin finish reduces slippage during handling. The ring end is set at a 15° angle to improve access on flat or tight surfaces, and clear size markings support quick identification in a toolbox. Weighing approximately 70 g, this compact hand tool is suitable for general mechanical, automotive and household fastening tasks.

Advantages

The drop-forged chrome-vanadium construction provides a balance of strength and toughness for repeated use. Hardened and tempered treatment increases wear resistance and longevity. The satin finish improves grip and reduces glare, while the 15° angled ring end enhances reach and torque application in confined spaces. Clear size markings speed up tool selection and reduce time spent searching. The combined open and ring ends allow one tool to cover multiple fastening needs.

Suitable for

• General mechanical maintenance and repairs
• Automotive tasks such as tightening and loosening fasteners
• Household assembly and repair jobs
• Workshop and light professional use where a compact wrench is needed

How to use

Select the wrench size that matches the nut or bolt, ensuring the open or ring end fully engages the fastener. For initial loosening or where clearance is limited, use the open end; for higher torque and a more secure grip use the ring end. Position the angled ring end when working on flat or recessed surfaces to improve access. Apply steady, controlled force and avoid sudden jerks. After use, wipe the tool clean and store it in a dry toolbox or on a tool rail to prevent corrosion and maintain markings visibility.

Usage recommendations

Do not use the combination wrench as a hammer or lever beyond its intended capacity. For stubborn or corroded fasteners, apply penetrating lubricant and allow time to work before attempting to turn. Regularly inspect the tool for wear or deformation and replace it if the jaws no longer seat properly to maintain safe and effective operation.
