The Sealey Torx/Hex/Spline Socket Bit Set 22Pc 3/8"Sq Drive is a comprehensive socket bit set designed for professional tradespeople requiring versatile fastener solutions. This 22-piece set combines three essential bit types in a single organised kit, providing mechanics, maintenance engineers and contractors with the tools needed for a wide range of applications. Manufactured from forged Chrome Vanadium steel sockets fitted with high-grade S2 steel hex bits, this socket bit set delivers exceptional strength and durability for demanding workshop environments. Each socket undergoes heat treatment before receiving a chrome-plated finish with a fully polished mirror surface, enhancing corrosion resistance and ease of cleaning. The set includes an extensive range of 50mm socket bits covering metric spline sizes (M4 through M12), TRX-Star sizes (T10 through T50), and hex sizes (4mm through 10mm). This comprehensive selection makes the kit ideal for automotive repair, machinery maintenance, and general engineering tasks where multiple fastener types are encountered. Practical design features include knurled rings on the sockets that improve grip even with oily fingers, ensuring secure handling in typical workshop conditions. The complete set arrives in a purpose-designed EVA storage tray that keeps bits organised and protected, whilst a lifetime guarantee provides long-term peace of mind.
