Open-end wrench Proxxon 23 046 — 9 mm, chrome‑vanadium, stainless finish, 1 piece

Proxxon 23 046 is a single 9 mm open-end wrench manufactured from chrome‑vanadium steel with a stainless finish. Designed for general mechanical and maintenance tasks, this compact 1-piece tool combines a slim open-ended jaw with a hinged 72‑tooth ring gear on the opposite end. The ring gear made of high-alloy steel enables ratcheting with minimal swing angle, while the chrome‑vanadium shaft with double nickel- and matt chrome-plating provides enhanced corrosion resistance and surface protection.

Advantages

The combination of a fixed open-end jaw and a hinged ring side gives both direct access and ratcheting convenience in one tool. The 72-tooth inner ring gear allows ratcheting with as little as a 5° movement, reducing repositioning in confined spaces. Laser-marked socket size improves visibility and selection, and the hardened CrV construction delivers strength that exceeds typical DIN/ISO torque requirements. The stainless finish and multi-layer plating increase resistance to wear and corrosion during regular workshop and automotive use.

Suitable for

• Automotive maintenance and repairs where space is limited
• Workshop and professional mechanical jobs requiring precise torque transmission
• Household and DIY tasks involving 9 mm fasteners
• Assembly and disassembly of machinery in confined or awkward positions

How to use

Select the 9 mm open-end wrench and position the open jaw on the fastener for direct turning, or place the hinged ring side over the fastener head for ratcheting action. When using the ring side, exploit the 72-tooth gear to work with minimal swing angle; move the wrench back and forth through small arcs to tighten or loosen bolts in confined areas. Apply steady, controlled force and avoid excessive impact loading to preserve the hardened surfaces and ratchet mechanism. Keep the tool clean and dry after use to maintain the plated finish.

Usage recommendations

For safe and durable performance, use the Proxxon 9 mm wrench within recommended torque limits for hand tools, avoid using cheater bars or excessive leverage, and store the wrench in a dry toolbox. Periodically inspect the hinged ring joint and ratcheting teeth for debris and lubricate lightly if needed to maintain smooth operation.
