The siegen 9 piece extra long imperial ball end hex key set is a professional grade hand tool set designed for accessing hard to reach fasteners in automotive, machinery and equipment maintenance applications. Manufactured from heat treated and hardened chrome vanadium steel with a corrosion resistant blackened finish, these keys deliver the strength and durability required for demanding workshop environments. The extra long design provides exceptional reach into recessed areas, with keys ranging from 90mm to 230mm in length. The ball end configuration allows each key to engage hex socket fixings at angles up to 30°, making it ideal for working in confined spaces or around obstacles where straight line access isn't possible. This versatility significantly reduces the time spent repositioning tools or disassembling components to access awkward fasteners. The set includes nine imperial sizes spanning 1 16 through to 3 8, covering the most commonly encountered fastener specifications in imported machinery, classic vehicles and american manufactured equipment. All keys are supplied in an easy access storage case with integrated hanging tag, ensuring organised tool storage and quick size identification on site or in the workshop.
