The Sealey 13 Piece Black Series Socket Set is a professional-grade 1/2" drive metric socket collection engineered for mechanics and technicians working with worn or damaged fixings. Manufactured from hardened and tempered Chrome Vanadium steel, this socket set features a fully polished black chrome finish that delivers excellent corrosion resistance in demanding workshop environments. The standout feature is the specially machined flutes within the socket walls, which enable these lock-on sockets to grip and turn fasteners that are up to 85% rounded. This innovative design not only protects worn or rusted fixings from further damage but also provides additional socket strength for high-torque applications. Each socket includes a knurled ring that delivers extra grip when working with oily or greasy hands, a practical detail that improves usability in real-world workshop conditions. The comprehensive 13-piece set covers the most commonly used metric sizes from 10mm through to 24mm, ensuring you have the right socket for automotive, agricultural and general mechanical maintenance tasks. The complete set is supplied on a socket rail for organised storage and quick size identification.
