The siegen 9 piece long metric ball end hex key set is a professional grade tool set manufactured from heat treated and hardened chrome vanadium steel with a durable blackened finish. This comprehensive set features long reach keys ranging from 75mm to 180mm in length, providing enhanced access to recessed fixings in automotive, machinery and equipment maintenance applications. The ball end design allows each key to drive fixings at angles up to 30°, making it ideal for working in confined spaces or accessing awkwardly positioned fasteners where a straight approach isn't possible. This versatility reduces time spent repositioning components and improves workflow efficiency for mechanics, engineers and maintenance professionals. Covering sizes from 1.5mm through to 10mm, the set delivers comprehensive metric coverage for most common applications. The tools are supplied in an easy access storage case with a hanging tag, keeping keys organised and readily identifiable on the workbench or in the van.
