Britool Hallmark 26 Piece 1/4" Drive Bi-Hex Socket Set Standard & Deep 4-14mm

The Britool Hallmark 26 Piece Bi-Hex Socket Set is a professional-quality socket collection designed for precision fastening applications in automotive, engineering, maintenance, and general workshop environments. Manufactured from high-quality Chrome Vanadium steel, this versatile set combines strength, durability, and reliable performance for everyday professional use.

The set includes both standard and deep bi-hex (12-point) sockets, covering popular metric sizes from 4mm to 14mm. The 12-point profile provides excellent fastener engagement and allows easier alignment in confined spaces, making the sockets ideal for applications where access is limited.

Each socket is clearly stamped with the renowned Britool Hallmark branding and its individual part number for quick and easy identification. Supplied in a precision-cut tool control foam tray, the set helps keep tools organised while fitting neatly into most toolbox drawers and workshop storage systems.

Individual replacement sockets are also available separately, allowing specific sizes to be replaced without purchasing a complete new set.
