Combination wrench AWTools AW39984, size unspecified, chrome-plated, weight 180 g

AWTools AW39984 combination wrench is a hand tool that combines an open-end spanner and a ring spanner with an integrated 72-tooth ratchet mechanism. Manufactured from chrome-vanadium (CrV) tool steel, the wrench is drop forged, hardened and tempered, then chrome plated with a polished finish to provide corrosion resistance. The tool features a 15° open-end angle for better accessibility in confined spaces, a 5° swing arc for fine ratcheting, and a direction switch lever to quickly change the ratchet from right to left. Clear size markings are stamped on the body and the unit weighs approximately 180 g.

Advantages

The combination of an open-end and ring-end with a 72-tooth ratchet provides efficient fastening and loosening without removing the wrench from the fastener. Chrome-vanadium construction with drop forging, hardening and tempering ensures mechanical strength and durability under regular use. The chrome-plated polished finish improves corrosion resistance and simplifies cleaning, while the 15° angle on the open end and the 5° swing arc increase accessibility and allow precise work in tight or awkward positions. A reversible switch lever speeds up direction changes for both tightening and loosening operations.

Suitable for

• Automotive maintenance and repair tasks
• General mechanical assembly and disassembly
• Household repairs and DIY projects
• Professional workshop use where a durable hand wrench is required

How to use

Select the correct size on the AWTools AW39984 to fit the nut or bolt. Position the open end or ring end on the fastener and, if using the ring end, set the ratchet direction with the switch lever to match the required tightening or loosening motion. Use the 5° swing arc to incrementally turn the fastener in confined spaces, and flip to the open end with its 15° offset when better entry angle is needed. Apply steady force along the wrench axis and avoid sudden impact loads; for high torque requirements use appropriate tools designed for those loads.

Usage recommendations

Keep the wrench clean and dry after use and store it in a tool roll or toolbox to protect the chrome finish. Inspect for wear or damage before each use and do not use the wrench on rounded fasteners or with cheater bars. For optimal longevity and safe operation, follow workshop safety practices and select the correct size and orientation when working on nuts and bolts.
