The Capri Tools 88-Piece Master Bit Socket Set is a complete collection of most frequently used bit sockets. We use premium S2 steel tempered with our proprietary heat treatment process to make these bits (other than 1/2 in. drive hex bits 9/16 in. / 14 mm and above). They are exceptionally durable and strong， withstand high torque and do not twist， protecting both the bit and the fastener. The 1/2 in. drive hex bits 9/16 in. / 14 mm and above are forged with our custom Chrome Vanadium steel， giving them a balance tensile strength for optimal performance. The sockets are constructed with premium Chrome Vanadium steel and plated with our own chrome protective plating - durable and resist corrosion. We made all of our hex bits true-to-size for their entire length， letting you use the full length of the hex bit. Chamfered end ensures a smooth fit onto fasteners. 88-piece set includes (13) external star sockets， (15) star bit sockets， (15) long star bit sockets， (16) hex bit sockets in metric， (7) long hex bit sockets in metric， (15) hex bit sockets in SAE， (7) long hex bit sockets in SAE. Meets and exceeds ASME B107.110 standards.
