The Sealey 26 Piece 3/8" Drive Spline Socket Bit Set is a comprehensive socket bit collection designed for working with spline fasteners across a wide range of automotive and mechanical applications. This professional socket set combines forged Chrome Vanadium steel sockets with durable S2 steel spline bits for reliable performance on spline-headed bolts commonly found in modern vehicles and machinery. Each socket features heat treatment and chrome plating to provide excellent corrosion resistance, ensuring longevity even in demanding workshop environments. The fully polished micro satin finish not only looks professional but also makes cleaning easier, while the knurled ring design assists with gripping when working with oily fingers – a practical feature that experienced mechanics will appreciate. The set offers exceptional versatility with 26 pieces across four different lengths: 48mm, 93mm, 140mm, and 200mm. This comprehensive range covers spline sizes from M5 through to M16, with multiple length options for M5, M6, M8, M9, M10, M12 and M14 sizes. The longer reach options are particularly useful for accessing recessed fasteners or working in confined spaces where standard length tools won't reach. All pieces are supplied in a storage case for organised transport and workshop storage, and the set is backed by a lifetime guarantee.
