Combination wrench AWTools AW39783, chrome-plated, weight 300 g

AWTools AW39783 combination wrench is a dual-ended hand tool that integrates an open-end spanner and a ring (boxed) spanner in one chrome-plated unit. Manufactured from chrome-vanadium (CrV) tool steel, the wrench is drop forged, hardened and tempered to meet mechanical demands. The satin finish reduces slippage while clear size markings enable quick identification. The ring end is angled 15° to improve access on flat surfaces; the tool complies with DIN 3113 and has a listed weight of approximately 300 g.

Advantages

The chrome-vanadium construction and heat treatment provide a balance of strength and toughness for repeated use in workshop and field conditions. Chrome plating offers corrosion resistance and facilitates cleaning after use. A satin finish reduces the risk of slipping in the hand or on fastener faces, while the 15° ring-end offset improves reach and usability in confined or flat-surface applications. Dual-end design eliminates the need to switch tools when alternating between open and boxed contact.

Suitable for

• Automotive maintenance and repair tasks
• General mechanical assembly and disassembly
• Household repairs and maintenance
• Workshop and professional use where DIN 3113 compliance is required

How to use

Select the correct size marked on the wrench to match the nut or bolt head. Position the open-end or the ring end over the fastener, ensuring full seating to reduce rounding. For confined spaces or flat-surface work, use the 15° angled ring end to gain access and leverage. Apply steady, controlled force; avoid sudden impacts. After use, wipe clean and store in a dry environment to maintain the chrome plating and markings.

Usage recommendations

Use the boxed ring end for maximum contact on fasteners to reduce rounding; reserve the open end for quick engagement and adjustments. Do not use the wrench as a hammer or pry bar. Inspect the tool periodically for wear or deformation, especially if subjected to high torque; replace if any damage is found to maintain safe operation.
