The Sealey 11 Piece 1/4" Drive Hexagon Socket Bit Set is a professional metric socket bit set designed for fastening applications across automotive, mechanical and general workshop tasks. Constructed from drop-forged Chrome Vanadium steel, these sockets are hardened and heat treated to withstand the demands of professional use, finished with a fully polished mirror finish for corrosion resistance and easy cleaning. The hexagon bits themselves are manufactured from S2 steel with a blackened finish that provides additional protection against corrosion in workshop environments. A key feature of this socket bit set is the 2mm hex setscrew integrated into each socket, allowing individual bits to be quickly replaced without needing to purchase an entire new set. This practical design extends the working life of the set and reduces long-term costs for busy workshops and mobile technicians. The comprehensive 11-piece metric range covers the most commonly required sizes from 1.5mm through to 11mm, making this set suitable for precision electronics work, automotive applications, and general mechanical assembly tasks. Supplied organised on a socket rail for convenient storage in toolboxes or workshop drawers, and backed by a lifetime guarantee.
