- Robust steel construction for strength and stability. Jaws and drive gear are made from 40Cr and 50CrV, designed for reliable performance under load. - Bright coating with a two-tone black grip for clear visibility and comfortable handling. Opposite side supports metric 6-22 mm and imperial 1/4-7/8 in fasteners; opposite-side size range 6.35–22.2 mm. - Key components are steel, produced by automatic machining and heat treatment using environmentally friendly materials, delivering consistent tolerances and long life. - Sleeve hanger protects the socket head from wear and reduces the risk of dropping in maintenance spaces. Includes a quick-clamp mechanism and a quick-disconnect function for fast, secure socket changes. - Rust resistance, wear resistance, and general hardened construction enhance durability in typical workshop conditions. Suitable for regular servicing, repair, and assembly tasks. Use scenarios: - Automotive and motorcycle maintenance: rapidly swap sockets for metric 6–22 mm and imperial 1/4–7/8 in fasteners, improving turnaround time. - Bicycle repair and equipment maintenance: work in tight spaces with secure, reusable sockets and quick-change capability. - Machinery servicing and industrial repair: durable, corrosion-resistant tools that handle repeated use and exposure to grime or moisture.
