Combination wrench AWTools AW39917, length unspecified, weight 260 g

AWTools AW39917 is a combination wrench made from chrome-vanadium (CrV) tool steel and designed for tightening and loosening nuts and bolts. The single-piece construction pairs an open-end jaw with a boxed ring end and features a flex head to improve accessibility in confined spaces. The wrench is drop forged, hardened and tempered, then chrome plated with a polished finish for corrosion resistance and easy cleaning. Known weight: 260 g. The tool includes a 72-tooth ratchet mechanism with a 5° swing arc and a switch lever for quick reversal of ratchet direction, meeting DIN 3113 standards for combination wrenches.

Advantages

The AWTools AW39917 combines an open-end spanner and a ring spanner in one tool, offering the flexibility to work on a wide range of fasteners without frequently changing tools. The 72-tooth ratchet and 5° swing arc allow fine incremental movement in tight conditions, while the switch lever enables fast direction changes. Drop forging, heat treatment and chrome plating provide strength, wear resistance and a smooth surface finish. Clear size markings make the correct tool easy to identify on the job.

Suitable for

• General mechanical maintenance and assembly

How to use

Select the AWTools AW39917 with the correct nominal size for the fastener. Place the open-end or ring end over the nut or bolt head and, when using the ring end, engage the ratchet mechanism. Use the switch lever to set the desired rotation direction. Work with short, controlled strokes, taking advantage of the 5° swing arc when space is limited. The flex head helps reach angled or recessed fasteners; apply steady pressure and avoid sudden impacts to preserve the tool’s heat-treated properties and ratchet mechanism.

Usage recommendations

For long service life, clean the wrench after use, keep the ratchet mechanism free of dirt and lubricate periodically. Use the correct size to minimize rounding of fasteners. Do not use the wrench as a hammer or extend the handle with pipes for extra leverage, as that may damage the tool or compromise safety. Store the wrench in a dry place to reduce corrosion despite the chrome finish.
