This professional socket from Promat is a high-quality tool for precise screwdriving tasks in industry and trade. With a wrench size of 11 mm and the standardized 1/2 inch (12.7 mm) internal square drive, it offers excellent stability for a wide range of assembly applications.
The special twelve-point profile (bi-hex) allows for significantly easier positioning of the socket on the screw, as it provides twice as many starting positions compared to a conventional hexagon. This is a decisive advantage for efficient work, especially in confined spaces.
Made from robust chrome vanadium steel, the socket is designed for extreme durability and high mechanical loads. The matt chrome-plated surface not only ensures a professional appearance, but also guarantees a secure grip—even when in contact with oil or grease—and provides reliable protection against corrosion.
Product features
