This 18-piece impact socket set provides a comprehensive solution for automotive repair, equipment assembly, and industrial applications. Crafted from durable CR-V industrial-grade alloy steel, these sockets withstand high torque and impact for reliable performance. The 3/8" drive size is compatible with a variety of tools, including electric wrenches, impact wrenches, and ratchet wrenches.
