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, not only provides an attractive appearance but also ensures high resistance to corrosion. The wrench features a skin-friendly finish and is equipped with a permanent laser engraving that clearly displays the sizes in millimeters. Despite its slim and thin-walled design, the ring-open-end wrench exceeds the required torque values according to DIN/ISO standards. The measurement tolerances are tighter than the standard specifications, ensuring precise application. Each piece is calibrated and undergoes a final inspection, making it perfectly suitable for commercial use.
