The Sealey 13 Piece Black Series 1/2" Drive Deep Lock On Hexagon Socket Set is a professional-grade socket set engineered for demanding workshop and on-site applications. Manufactured from hardened and tempered high grade Chrome Vanadium steel, this comprehensive set delivers exceptional durability and strength for automotive, mechanical and maintenance work. The distinctive black chrome finish provides superior corrosion resistance whilst reducing glare under workshop lighting. Each deep socket features specially machined flutes in the walls which enable reliable engagement with up to 85% rounded fasteners, making this set particularly valuable for working with seized, corroded or damaged fixings where standard sockets would slip. The Lock-On hexagon design combines the fluted internal profile with added socket wall strength to prevent further damage to worn threads and rusted bolts. A knurled ring on each socket ensures secure grip even with oily or greasy fingers, essential for real-world workshop conditions. The complete set spans from 10mm to 24mm and is supplied organised on a socket rail for efficient storage and quick size identification.
