The Capri Tools 1/2 in. Drive Stubby Impact Socket Set is perfect for working in tight spots. The stubby size is 20% shorter than shallow length sockets. We use premium Chrome Molybdenum steel tempered with our proprietary heat treatment process to make these impact sockets and accessories. They are durable and specifically made to withstand high torque from power tools. Each item is expertly coated with manganese phosphate, the preferred coating in military and aerospace, which offers superior protection and corrosion resistance compared to black oxide coating on other impact sockets. The 6-point WaveDrive design grips fasteners more tightly than traditional design, preventing fastener rounding and giving you more leverage. Meets and exceeds ASME B107.110 standards. 15-piece set includes 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1 in., organized by size in a convenient impact-resistant tool case.
