The draper 40 piece 1 4 drive hex socket set delivers comprehensive coverage for professional tradespeople and serious diy enthusiasts working with both metric and imperial fixings. This socket set combines 21 sockets spanning popular sizes with a versatile range of drive accessories, all housed in a durable storage case for workshop or mobile use. Each six point socket is manufactured from chrome vanadium steel that's been hardened and tempered for long term durability, finished with a micro satin surface that resists corrosion whilst remaining easy to clean. The knurled grip ring on each socket provides additional purchase when hand tightening or loosening stubborn fasteners in confined spaces. The 72 tooth reversible ratchet offers fine control with minimal swing arc required, making it ideal for working in restricted access areas where full rotation isn't possible. Three wobble extension bars in graduated lengths provide the reach and flexibility needed for recessed fixings, whilst the included universal joint and sliding t bar expand your working options. The hex bit adaptor and comprehensive selection of insert bits transform this socket set into a multi purpose fastening toolkit suitable for automotive work, appliance repair, machinery maintenance and general mechanical tasks.
