The TEKTON 3/8 in. Drive 6-Point Socket and Ratchet Set (SKT15311) is a comprehensive 73-piece master set designed for mechanics and serious DIY enthusiasts. It includes every size from 1/4 to 1 inch (SAE) and 6 to 24 mm (Metric) in both deep and standard lengths, with no skipped sizes. The 6-point sockets are engineered to grip the flat sides of fasteners, preventing round-off. The set features a finely geared 90-tooth quick-release ratchet, requiring only a 4-degree working swing arc for use in tight spaces, as well as a long breaker bar and accessories.
