The Astro Pneumatic 78354 is a 10-piece 3/8" Drive 6-Point Pinless Universal Torque-Saver Impact Extension Socket Set designed for professional technicians who demand maximum torque transfer in tight or awkward spaces. This metric set covers every size from 10mm to 19mm with no skipped sizes, each socket built on a 9-inch-long impact extension with a pinless universal joint end. Forged from Chrome Molybdenum Steel, these extensions are engineered for durability under heavy-duty impact use. The exclusive Torque-Saver design delivers measurably more torque than competing universal extension sockets, and a lifetime warranty backs every piece in the set.
