The Sealey 13 Piece 1/4" Drive Total Drive Socket Set is a comprehensive metric socket collection designed for professional tradespeople and serious DIY users. Manufactured from chrome vanadium steel, each socket is hardened and heat treated to deliver exceptional strength and durability, whilst the fully polished mirror finish provides excellent corrosion resistance for long-term reliability. The Total Drive® technology allows these sockets to be used across a remarkably wide range of fastener types, making this a versatile addition to any toolbox. Each socket is compatible with Spline, Metric Hex and Bi-Hex fasteners as standard, with many sizes also suitable for use with TRX-Star*, Whitworth, Imperial Hex and Imperial Bi-Hex fittings. This multi-fastener capability reduces the need for multiple socket sets and simplifies tool selection on the job. Practical features include a knurled ring design that provides secure grip even when working with greasy or oily hands - a common scenario in automotive, machinery and general maintenance work. The 13-piece set covers metric sizes from 4mm through to 14mm, including half-millimetre increments in the smaller sizes for precise fastener matching. All sockets are supplied on a storage rail for organised transport and quick size identification, and are backed by a lifetime guarantee.
