The faithfull 13 piece long ball end hexagon allen key set is a professional grade metric hex key collection designed for tradespeople requiring versatile access to fasteners in challenging locations. Manufactured from fully hardened chrome vanadium steel, this comprehensive set delivers the durability and precision expected on professional job sites. The long arm design provides extended reach for deep set screws and difficult to access fixings, whilst the ball end configuration allows angle entry up to 25 degrees. This angled capability significantly improves access in confined spaces and speeds up insertion and removal compared to standard hex keys. Keys from 4mm upwards feature chamfered edges to prevent damage to both the blade and fittings during use. The set arrives in an ergonomic double layer, open out storage caddy that ensures smaller keys remain accessible and organised. Each key is housed in a dedicated, clearly marked space for quick identification and secure storage between jobs. This practical organisation makes the set ideal for workshop and mobile applications where tool accountability and efficiency matter. Covering an extensive metric range from 1.3mm through to 10mm, this 13 piece collection provides comprehensive coverage for general mechanical work, assembly tasks, and maintenance applications across multiple trades.
