1/4 Inch Drive Hex Bit Socket Set with Rails, 21-Piece (5/64-5/16 in., 2-8 mm)

Tekton Bit Sockets have heat-treated S2 steel bits that are press-fit into the socket for a straight, tightly mated fit that can't loosen over time or under stress. The tips are machined to precise tolerances for an exact fit with hex fasteners. 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.
