To further enhance accessibility to tough-to-reach fasteners, the ratchet is designed with an unlocking button that releases a hinge mechanism in the tool\'s head, allowing the head to flap 90 degrees in either direction. The reversible ratchet is a mere 4 1/2\" in length and comes in a super compact (4 3/4\" x 2 3/8\" x 1 1/8\") storage case that you can carry in your pants pocket. The set includes the following sockets ranging from 5.5 to 14mm with sizes clearly marked on the socket and in the box for quick access. Facing a tight squeeze? Here\'s your socket set. Includes: Swivel-head ratchet for short sockets (11mm bi-hexagonal opening) Hexagonal short sockets: 5.5, 6, 7, 8, 9, 10, 11, 12, 13, 14mm
