Combination wrench AWTools AW39770, weight 60 g, hand tool, metric/open-end and box-end

AWTools AW39770 is a compact combination wrench designed for manual tightening and loosening of metric fasteners. Manufactured from chrome-vanadium (CrV) tool steel, the single-piece spanner combines an open-end and a box-end (ring) to offer two working options in one tool. The wrench is drop forged, hardened and tempered to increase strength and wear resistance, and finished with a satin surface to reduce slippage. The ring end is set at a 15° angle to improve accessibility on flat surfaces, and clear size markings simplify fastener identification. With a listed weight of 60 g, this spanner is suitable for workshop, automotive and household tasks where a compact, reliable hand tool is required.

Advantages

The AWTools AW39770 provides a dual-function design that saves space in a toolkit and reduces the need to switch tools during work. Chrome-vanadium construction with drop forging, hardening and tempering ensures consistent mechanical strength and long service life under regular use. The satin finish helps maintain grip and reduces the risk of slipping on oily or greasy parts. A 15° angled ring end increases access to fasteners on flat or confined surfaces, while clear etched size markings speed up tool selection.

How to use

Select the appropriate size by checking the clear size markings on the wrench. Place the open end over the flats of the fastener for quick turning where space allows, or use the ring end to engage more contact area for higher torque and reduced rounding risk. When using the ring end, orient the 15° angle to improve access on flat or crowded surfaces. Apply steady, controlled force and avoid sudden impacts. After use, wipe the wrench clean of grease and store it in a dry toolbox or rack to prevent corrosion and maintain the satin finish.

Usage recommendations

Use the AWTools AW39770 with compatible metric fasteners of the marked size and avoid using it on damaged or rounded bolts. Do not use the wrench as a hammer or pry bar. For tasks requiring higher torque, use the ring end and ensure full contact with the fastener flats. Regularly inspect the tool for wear or deformation and replace if any cracking or significant wear is detected.
