TEKTON 3/4 Inch Drive Sockets are well-suited for big service and repair jobs on heavy equipment, trucks, tractors, and large machinery. The 6-point socket opening is ideal for working with hex-shaped fasteners and is designed to grip the sides and not the corners of the fastener heads, preventing round-off. The large, die-stamped markings are permanently impressed into the material and optimized for readability. A mirror chrome-plated finish protects against corrosion and easily wipes clean. TEKTON 3/4 Inch Drive Sockets are available in a complete range of sizes from 3/4 to 2 inch and consistently meet or exceed the industry standards for socket strength and performance. Material: Chrome-Plated Steel.
