These ICON™ Professional Hex-Bit Sockets are made with precision-milled S2 steel tips for a perfect fit when removing and replacing hex fasteners. The ultra-tough chrome-vanadium steel sockets have a premium chrome finish that not only looks great, but easily wipes clean and resists corrosion. Like the rest of the ICON™ hand tools, these sockets are backed by a hassle-free, manufacturer’s lifetime warranty.
