The Draper Expert 40 Piece Torx, Hexagon and XZN Socket Bit Set is a comprehensive socket bit collection designed for professional mechanics and technicians working with modern fasteners. This versatile set combines Torx, hexagonal and XZN spline bits in both 30mm and 75mm lengths, offering the range required for automotive and machinery applications. Manufactured from high-grade S2 silicon steel, the insert bits are hardened and tempered with a shot blasted finish to resist wear and corrosion. The two bit holders feature chrome vanadium steel construction with chrome plating for durability, converting between 3/8" and 1/2" square drives to accommodate different ratchets and torque wrenches. The set provides extensive coverage with seven Torx sizes from T20 to T55, seven hexagonal sizes from 4mm to 12mm, and five spline sizes from 5mm to 12mm. This makes it particularly suitable for automotive work including brake callipers, engine components and modern vehicle assemblies that increasingly use security fasteners. The steel storage case keeps bits organised and protected, whilst spare bits remain available for individual replacement when required.
