The Draper Expert 150 Piece Combination Drive Socket Set delivers comprehensive coverage for professional mechanics and technicians who work with both metric and imperial fasteners. This extensive socket and accessory collection spans three drive sizes – 1/4″, 3/8″ and 1/2″ – providing the versatility needed for automotive repairs, machinery maintenance and general engineering tasks. Manufactured from chrome vanadium steel that’s been hardened and tempered, each six-point socket features a micro satin finish for corrosion resistance and a knurled ring for secure handling. The set includes standard and deep sockets across all three drive sizes, along with wobble extension bars for accessing awkward positions. Three 72-tooth reversible ratchets with soft-grip handles and quick-release buttons deliver precise control in restricted spaces, requiring just 5 degrees of swing arc to operate effectively. Beyond sockets, this comprehensive toolkit includes 10 combination spanners and 24 insert bits covering plain slot, cross slot, Pozi-drive, hex and TX-STAR profiles. The universal joints and drive adaptors expand compatibility across different fastener applications. Two spark plug sockets handle common automotive ignition work. Everything stores securely in a robust plastic case with soft-grip handle for workshop organisation and mobile service work.
