The Proxxon ring-open-end wrench is a high-quality tool designed for professional applications. Made from robust chrome-vanadium steel, this wrench offers excellent durability and longevity. The elaborate surface treatment, consisting of two layers of nickel plating and one layer of chrome plating, not only provides an appealing appearance but also ensures a skin-friendly finish. The polished heads are slim and thin-walled, allowing for easy handling and access to tight spaces. With a permanent laser engraving, the sizes in millimeters are clearly and distinctly readable. The ring-open-end wrench not only meets the requirements of DIN/ISO standards but also exceeds them in terms of torque values and measurement tolerances. Each piece is calibrated and subjected to strict final inspection to ensure the highest precision and reliability.
