The Kincrome Socket Set 1/2 Drive Metric/SAE 42 Piece is a comprehensive hand-tool kit suited to professional tradespeople and dedicated DIYers who need metric and imperial coverage from a single case. Chrome vanadium steel construction keeps every socket strong and wear-resistant through years of regular use, while 12-point socket design engages fasteners squarely even in tight access situations. The set spans 19 metric sockets from 8mm to 32mm and 15 SAE sockets from 3/8 in to 1-1/4 in, all paired with a 375mm flex handle, ratchet handle, universal joint and three extension bars (75mm, 125mm and 250mm) for reach and versatility. Spark plug sockets in 16mm and 21mm are included for engine servicing, and everything stores in a sturdy powder-coated metal case with a plastic organiser insert for quick identification and safe transport.
