Siegen 9 Piece Long Hexagon Allen Key Set

The Siegen 9 Piece Long Hexagon Allen Key Set is a professional-grade hex key collection designed for accessing recessed fasteners in confined spaces. Manufactured from heat treated and hardened Chrome Vanadium steel, these keys deliver the strength and durability required for demanding workshop and site applications. The blackened finish provides corrosion resistance whilst reducing reflective glare during use. With keys ranging from 1.5mm to 10mm and lengths spanning 90mm to 230mm, this comprehensive set covers the most commonly encountered metric hex fastener sizes. The extended reach is particularly valuable when working with deeply recessed bolts or fixtures where standard length keys cannot provide sufficient access. The set is supplied in an easy-access storage case with a hanging tag, allowing quick key selection and organised tool storage. This makes it ideal for mobile mechanics, maintenance engineers, and workshop technicians who need rapid access to the correct size key. Th
