The USAG 285/B12 is a professional 12-piece metric combination spanner set covering sizes 8 mm to 19 mm — the range you reach for most during kart preparation, trackside maintenance and general workshop work. Each spanner features a combination design with an open-ended jaw and a ring end, both angled at 15° for improved access in confined spaces and on recessed fasteners.

For karting use, a well-specified combination spanner set is one of the most-used tools in the paddock. From adjusting seat struts and floor tray fixings to working on hub nuts, engine mounts and brake components, the 8–19 mm range covers the majority of metric fasteners found across a kart chassis and its ancillaries. The included fabric pouch keeps the set organised and protected, making it a practical addition to any race van or trackside tool kit.
