The Draper 16482 is a 19 piece socket set manufactured from chrome vanadium steel, which has been hardened and tempered with a polished finish. The unique hollow socket technology of the Draper Expert ‘Go Through’ ratchet and sockets, is ideal for long fixings and the sockets are edge driven. This allows a fixing to pass through the head and avoid the depth restriction of conventional sockets and ratchets. The set is completed with the included tough plastic storage case with soft grip handle.
