The siegen 9 piece long imperial ball end hex key set is a professional grade hand tool kit designed for accessing recessed fixings in challenging applications. Manufactured from heat treated and hardened chrome vanadium steel with a blackened finish, this set delivers the durability and corrosion resistance demanded by trade professionals and serious diy enthusiasts. The ball end design allows each key to drive fixings at angles up to 30°, making this set ideal for working in confined spaces where straight access isn't possible. With keys ranging from 75mm to 180mm in length and covering sizes from 1 16 to 3 8, the set provides comprehensive coverage for imperial fasteners commonly found in automotive, machinery maintenance, and equipment assembly applications. Supplied in an easy access storage case with hanging tag, the set ensures quick size selection and safe organisation in the workshop or on site. The extended length of these keys provides enhanced reach and improved leverage compared to standard hex keys, particularly useful when working deep within machinery housings or vehicle assemblies.
