Combination wrench AWTools AW39781, weight 240 g, open and box ends, hand tool

AWTools AW39781 is a combination wrench designed for general mechanical and maintenance tasks. Manufactured from chrome-vanadium (CrV) tool steel, the one-piece wrench combines an open end and a box (ring) end to provide versatility for tightening and loosening fasteners. The tool is drop forged, hardened and tempered to improve durability, and features a satin finish to help reduce slippage. The ring end is set at a 15° angle to improve accessibility on flat surfaces, and clear size markings simplify identification during work. With a stated mass of 240 g, this hand tool complies with the DIN 3113 standard and is suitable for use in workshops, garages and on-site repairs.

Advantages

The combination of an open end and a ring end in a single wrench provides practical versatility for a wide range of fastener access situations. Chrome-vanadium construction with drop forging, hardening and tempering delivers strength and resistance to wear in regular professional and amateur use. A satin finish reduces the risk of slipping during handling, while the 15° angled ring end improves clearance on flat surfaces and allows incremental repositioning. Clear size markings make it easier to choose the correct tool quickly.

Suitable for

• General mechanical maintenance and assembly work
• Automotive repairs and component adjustments
• Plumbing tasks involving nuts and bolts
• Workshop and garage use for routine tightening and loosening
• On-site repair and service jobs requiring a compact hand tool

How to use

Select the AWTools AW39781 combination wrench with the correct size for the fastener. Position the open end or the angled ring end on the nut or bolt head as required by the working space. Apply steady force to turn the fastener; use the ring end for better grip and torque, and the open end where access or rapid repositioning is needed. Avoid using excessive force or using the wrench as a hammer. After use, clean the surfaces from dirt and residues and store the tool in a dry toolbox or on a rack to prevent corrosion.

Usage recommendations

Use the ring end for high-torque operations and confined spaces, and the open end for quick placement and initial loosening. Keep the wrench clean and inspect for deformation or wear before professional use. For work requiring impact force or extreme torque, use appropriate tools designed for those conditions rather than this hand wrench.
