ICON™ sockets are among the best available on the market. We use a premium chrome vanadium steel, with a high polished finish that not only looks great, but easily wipes clean and resists corrosion. All hex socket bits are constructed with premium S2 steel, delivering outstanding strength and durability. We didn’t skip sizes in the sets either, ensuring that you’ll always have the right tools for the job. 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™ hand tools, these sockets are backed by a hassle-free, manufacturer’s lifetime warranty.
