The Proxxon ring-open-end wrench is a high-quality tool made from CrV steel, carefully hardened and tempered. The elaborate surface treatment, consisting of two layers of nickel plating and one layer of chrome plating, ensures high durability and a skin-friendly finish. The polished heads are slim and thin-walled, allowing for easy handling. Despite its compact design, the wrench exceeds the torque values required by DIN/ISO and offers tighter measurement tolerances. Each piece is calibrated and subjected to a final inspection, ensuring the tool's suitability for commercial use. The permanent laser marking and large, easy-to-read sizes in millimeters enhance user-friendliness, making this ring-open-end wrench an essential tool for professional applications.
