ICON™ professional impact sockets are among the best available on the market. We use a premium heat treated chrome moly steel, with an ultra durable black phosphate finish that offers superior corrosion resistance. The 360° swivel head provides easy access to hard-to-reach nuts and bolts. We’ve also added easy to read size markings, and included a premium storage tray to help keep your tools organized. Like the rest of the ICON™ tools, these sockets are backed by a hassle-free, manufacturer’s lifetime warranty.
