Combination wrench AWTools AW39983, weight 150 g, single open/box spanner

AWTools AW39983 is a combination wrench that integrates an open-end spanner and a ring spanner in one compact tool. Made of chrome-vanadium (CrV) tool steel, the wrench is drop forged, heat treated and chrome plated with a polished finish. It features a 72-tooth ratchet with a 5° swing arc and a switch lever for quick change of ratchet direction, while the open end is angled at 15° to improve accessibility in confined spaces. The tool is designed for tightening and loosening nuts and bolts in mechanical, automotive and household tasks and meets DIN 3113 standard.

Advantages

The combination of an open jaw and a closed ring end provides both quick engagement and a secure grip on fasteners, reducing the need to switch tools. The 72‑tooth ratchet mechanism and 5° swing arc allow precise operation in limited-clearance situations, while the direction switch enables efficient right/left operation without repositioning. Chrome-vanadium construction, drop forging, hardening and tempering deliver strength and durability, and the polished chrome plating protects against corrosion and facilitates cleaning. Clear size markings simplify fast identification during work.

Suitable for

• General maintenance and repair of machinery and equipment
• Automotive repairs and servicing
• Home and DIY projects involving nuts and bolts
• Amateur and professional mechanical work requiring compact, ratcheting wrenches

How to use

Select the appropriate size by checking the clear size markings on the wrench. Place the open end over the nut or bolt for quick initial engagement or use the ring end with the ratchet for secure contact and continuous turning without removing the tool. Use the switch lever to change ratchet direction as needed. Work within the wrench's torque and application limits and avoid applying extreme force beyond the tool's design to prevent damage.

Usage recommendations

Inspect the tool before use for wear or damage, keep the ratchet mechanism clean and lightly lubricated, and store the wrench in a dry place to maintain the chrome plating. For tasks requiring higher torque, use an appropriately sized wrench or torque tool rather than increasing force on this combination wrench.
