1/4 Inch Drive Universal Joint Socket Set with Rails, 16-Piece (1/4-9/16 in., 6-14 mm)

Tekton Universal Joint Sockets have a compact design for tight spaces. The sockets have a 4-pin joint design that reduces the overall height of the socket compared to a universal joint adapter with a shallow socket. The compact joint rotates smoothly and continuously at up to a 55-degree angle. The shallow 6-point socket opening provides an exact fit and maximum contact for hex fasteners. Radiused corners prevent fastener round-off by applying force to a fastener's flat sides, rather than its corners. Large stamped size markings are permanently impressed into the material by a roll-stamp die. Detent grooves and beveled edges provide a smooth and secure connection with the drive tool. The portable organization rails have twist-to-lock clips that hold sockets securely and can be repositioned anywhere along the rail.
