The Sealey 9 Piece Lock On Ball End Hex Key Set Imperial is a professional-grade tool set engineered to tackle stubborn fasteners in imperial sizing applications. Manufactured from Chrome Molybdenum steel with a polished satin finish, this set delivers exceptional durability and corrosion resistance for demanding workshop and site environments. The standout feature is the patented twist design on the short arm, which grips tighter as it turns, preventing fasteners from rounding and making light work of rusted, damaged or severely rounded hex head fixings. This innovative design proves particularly valuable when working with seized or corroded fasteners that would defeat standard hex keys. Each key features a ball-end design allowing you to drive fixings at angles up to 25°, providing improved accessibility in confined spaces and awkward installations. The set covers a comprehensive range of imperial sizes from 1/16" through to 3/8", with key lengths spanning 88mm to 225mm to suit various applications. Supplied in an easy-access storage case with hanging tag, the set keeps your keys organised and readily identifiable on site or in the workshop. Ideal for mechanics, maintenance engineers and contractors working with imperial fasteners, particularly on imported machinery, automotive applications and older equipment.
