AWTOOLS AW39779 combination wrench

The AWTOOLS AW39779 combination wrench is a durable hand tool designed for fastening and loosening nuts and bolts. Made of chrome-vanadium (CrV) tool steel and produced by drop forging, this wrench is hardened and tempered to provide strength and wear resistance. One end features an open-ended spanner while the opposite end has a ring spanner set at a 15° angle to improve access on flat or confined surfaces. The satin finish reduces slippage and clear size markings allow quick identification during work. The tool is suitable for both amateur and professional use and conforms to DIN 3113 standards.

Advantages

The combination of chrome-vanadium steel and heat treatment ensures high durability and resistance to deformation under load. The satin finish improves grip and reduces glare, helping to maintain control during use. The 15° angled ring end enhances accessibility in tight spots, while clear size markings speed up tool selection. At approximately 180 g, the wrench balances strength and manageable weight for extended tasks.

How to use

Select the correct size by checking the clear markings on the wrench and position the appropriate end on the fastener. Use the open end for quick application and the ring end for a more secure grip on nuts and bolts. When using the ring end at the 15° angle, orient the wrench to maximize clearance when working near flat surfaces. Apply steady force, keeping your hand aligned with the handle to minimize slipping and avoid sudden impacts that could damage the tool or fastener.

Usage recommendations

Inspect the wrench before use for any signs of wear or damage. Use the tool for its intended purpose and avoid excessive torque beyond recommended limits. Clean and store the wrench in a dry place to prevent corrosion and maintain the satin finish. For repetitive professional tasks, combine this tool with quality sockets or torque-controlled equipment where precise torque is required.
