Combination wrench set AWTools AW39815 — 12 pcs, total weight 1.4 kg

AWTools AW39815 — 12-piece combination wrench set, total weight 1.4 kg, made of chrome-vanadium (CrV) tool steel and supplied in a practical roll-up case with holes for hanging. Each wrench integrates an open-end spanner on one side and a ring (box) end on the other, with the ring end angled at 15° to improve accessibility on flat surfaces. The set is drop forged, hardened and tempered, finished with a satin surface to reduce slippage, and features clear size markings for quick identification. The design meets the DIN 3113 standard and is suitable for both amateur and professional use in general mechanical maintenance, automotive repairs and assembly tasks.

Advantages

The combination of open and ring ends in a single tool increases versatility and reduces the number of separate wrenches required. Chrome-vanadium construction with drop forging, hardening and tempering provides durability and resistance to wear. Satin finish improves grip and reduces reflection, while clear size markings speed up tool selection. The 15° angled ring end allows easier engagement on fasteners in confined or flat-surface positions. The included roll-up case keeps the set organized and ready for storage or transport.

Suitable for

• General mechanical maintenance and workshop tasks
• Automotive repairs and routine vehicle servicing
• Assembly and disassembly of machinery and equipment

How to use

Select the correct wrench size using the stamped markings and position the ring or open end on the fastener. Use the ring end for greater contact and reduced risk of rounding fastener heads; use the open end where space or alignment requires it. The 15° ring angle can be used to flip the wrench for incremental turning in confined spaces. Apply steady force along the wrench axis, avoid sudden impacts, and keep hands clear of pinch points. After use, clean tools of grease and debris and return them to the roll-up case to maintain organization and protect the finish.

Usage recommendations

For safe and long-lasting performance, use the ring end whenever possible to minimize fastener damage. Avoid using the wrenches as hammers or pry bars. Store the set in the supplied roll-up case and keep tools dry to prevent corrosion. For demanding industrial applications, inspect tools regularly for wear or deformation and replace damaged items.
