Combination wrench AWTools AW39990, 320 g, hand tool

AWTools AW39990 is a combination wrench designed as a manual hand tool for tightening and loosening fasteners in workshop, automotive and household repair tasks. The single-piece design integrates an open-end spanner and a ring spanner with a 72-tooth ratchet, providing the convenience of a ratcheting box end together with the accessibility of an angled open end. The tool is made of chrome-vanadium (CrV) tool steel, drop forged, hardened and tempered, then chrome plated with a polished finish for corrosion resistance and easy cleaning. The wrench weighs approximately 320 g and complies with DIN 3113 standard.

Advantages

The AWTools AW39990 combines an open end with a ratcheting ring end to reduce the need for multiple tools and speed up repetitive tightening or loosening operations. The 72-tooth ratchet mechanism and 5° swing arc allow fine incremental movement in confined areas, while the 15° open-end angle improves access when working near obstructions. Durable chrome-vanadium construction with drop forging, hardening and tempering ensures strength and wear resistance for both amateur and professional use. Clear size markings on the body make identification quick during busy workflows.

Suitable for

• Automotive maintenance and repair
• General workshop mechanical tasks
• Household repairs and assembly

How to use

Select the correct size on the AWTools AW39990 for the fastener and place the open end or the ratcheting ring end onto the nut or bolt head. Use the open end for initial loosening where clearance is limited, then switch to the ratcheting ring end to continue turning without removing the tool between strokes. Change ratchet direction with the switch lever to tighten or loosen as needed. Apply steady, even force and avoid sudden impacts; the tool is intended for manual use and not for powered impact tools.

Usage recommendations

To maintain performance and safety, keep the wrench clean and lightly oiled at the ratchet mechanism, inspect for wear or damage before use, and store in a dry place. Use the correct size to prevent rounding fasteners and follow torque guidelines appropriate for the application.
