Combination wrench AWTools AW39774 — AW39774, hand tool for tightening and loosening fasteners

AWTools AW39774 is a combination wrench engineered for tightening and loosening nuts and bolts in mechanical, automotive and general maintenance work. Manufactured from chrome-vanadium (CrV) tool steel, the spanner is drop forged, hardened and tempered to provide a balance of strength and durability. One end is an open-ended spanner and the opposite end is 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 help with fast identification during tasks.

Advantages

The AWTools AW39774 combines the speed of an open-end jaw with the secure contact of a ring end, allowing both rapid engagement and torque application without changing tools. Heat treatment and chrome-vanadium construction give the wrench resistance to bending and wear while maintaining adequate toughness. The 15° angled ring end increases accessibility in tight spaces and on flat surfaces, and the satin finish provides a reduced risk of hand slippage. Conformance to DIN 3113 ensures consistent dimensions and fit for standardized fasteners.

Suitable for

• Automotive repairs and maintenance

How to use

Select the AWTools AW39774 size that matches the fastener and position the open or ring end squarely on the nut or bolt head. For rapid engagement or working on rounded edges use the open end; for higher torque and secure contact use the ring end. When using the ring end, take advantage of the 15° angle to approach the fastener from a more ergonomic position on flat surfaces or where clearance is limited. Apply controlled force and avoid sudden impacts; do not use the wrench as a hammer or with added leverage such as cheater bars.

Usage recommendations

The tool is suitable for both amateur and professional use. For long service life, keep the wrench clean and dry, periodically check for wear or deformation, and store it in a toolbox or on a rack. Use appropriate personal protective equipment and select the correct size to avoid rounding fasteners.
