The siegen 9 piece long ball end hexagon allen key set is a professional quality hex key collection designed for engineers, mechanics and tradespeople working with hexagon socket fasteners. Manufactured from heat treated and hardened chrome vanadium steel with a satin finish, this comprehensive set provides durability and long term performance in demanding workshop environments.

This versatility is particularly valuable when working on machinery, automotive components, or furniture assembly where space constraints are common. Keys range from 62.5mm to 177mm in length and cover sizes from 1.5mm to 10mm, providing a complete range for most professional applications.
