The Astro Pneumatic 7831409 Stubby Impact Socket Set is engineered for maximum access in tight or obstructed areas. Each socket measures only 0.88 inches long, making them 35 percent shorter than shallow impact sockets and 15 percent shorter than other stubby impact sockets. A 17mm outside hex allows additional turning access when used with a wrench. The sockets are constructed from forged CR MO steel with increased material thickness between the socket body and drive for added durability and strength. Designed for demanding impact applications, this compact set provides reliable performance in professional automotive environments.
