Combination wrench AWTools AW39981, size unspecified, weight 110 g, chrome finish

AWTools AW39981 is a combination wrench engineered for general mechanical and maintenance tasks. It integrates an open-end spanner and a ring (box) end with a 72-tooth ratchet mechanism, providing a balance of accessibility and continuous turning. The tool is made from chrome-vanadium (CrV) tool steel, forged, hardened and tempered, and finished with chrome plating and a polished surface. With a lightweight construction of approximately 110 g and a compact profile, it is suitable for use in workshops, garages and household repair projects.

Advantages

The combination of an open-ended spanner and a ratcheting ring end allows both quick fitment in confined spaces and efficient continuous rotation without repositioning. The 72-tooth ratchet delivers a 5° swing arc for fine incremental movement, while the switch lever enables rapid change of ratchet direction between tightening and loosening. A 15° open-end angle improves accessibility on offset fasteners, and clear size markings simplify tool selection. Durable CrV construction with drop forging, hardening and tempering, plus chrome plating, offers corrosion resistance and long-term service life.

Suitable for

• General mechanical repairs and maintenance in workshops and garages
• Assembly and disassembly of machinery components and automotive fasteners
• Household and DIY projects requiring both open and boxed access
• Professional service tasks where compact ratcheting action speeds workflow

How to use

Select the correct size of the AWTools combination wrench for the fastener, align the open or ratcheting box end onto the nut or bolt, and apply controlled force to turn. Use the open end where lateral access is required or when initial engagement is needed, and switch to the ratcheting ring end to continue turning without removing the tool from the fastener. Use the lever to change ratchet direction for tightening or loosening. Maintain steady, straight force to reduce the risk of slipping and fastener damage.

Usage recommendations

Inspect the wrench before use for signs of wear or damage; do not use on rounded or damaged fasteners. For high-torque requirements use an appropriately sized tool and avoid excessive leverage on the wrench. After use, wipe clean and store in a dry place to preserve the chrome finish and prevent corrosion.
