Need a tough socket for your impact wrench? This IRWIN 6-inch square #2 socket is built for the job. It's an impact-grade socket, meaning it's made from hardened steel to withstand the high torque and vibrations of an impact driver without cracking or shattering. The 1/2-inch drive is standard for many heavy-duty impact wrenches. The \#2\ refers to the square size, which is a common size for larger bolts and nuts, often found in automotive, construction, or agricultural applications. It comes as a single socket, perfect if you need to replace a worn-out one or add a specific size to your set. IRWIN is a trusted name in tools, so you know you're getting quality. If you're doing serious mechanical work, this is the socket you want on your impact gun.
