Mechanics and DIYers, this 3-piece impact socket set is perfect for working on wheels! You get three essential sizes: 17mm, 19mm, and 21mm - the most common sizes for lug nuts. They're deep sockets with thin walls, so they fit into tight spaces where regular sockets won't. Made from chrome-molybdenum steel (CR-MO) that can handle the torque of impact wrenches without cracking. 1/2-inch drive fits most impact guns and breaker bars. Brand new, unbranded but good quality. The protective sleeve helps prevent damage to your lug nuts. Whether you're rotating tires, doing brake work, or any automotive job involving wheels, these sockets make the job faster and easier. A must-have for any garage!
