The Draper 3 Piece Socket Converter Set provides essential drive size adaptability for professional mechanics and engineers working with socket sets. This converter set enables you to use sockets and accessories across different drive sizes, maximising the versatility of your existing socket collection without the need for duplicate tools. Manufactured from chrome vanadium steel, each converter is hardened and tempered to withstand the rigours of professional workshop use. The polished chrome plated finish provides excellent corrosion resistance whilst making the converters easy to identify in busy toolboxes and socket organisers. The set includes three of the most commonly required drive combinations in metric workshops, allowing you to step up or step down between 1/4", 3/8" and 1/2" drive sizes. This makes the set ideal for automotive technicians, plant engineers and mobile mechanics who regularly work with multiple socket drive sizes across different applications and fastener types
