The Astro Pneumatic 78214 Low Profile Nano Impact Socket Set includes 14 metric sockets from 17mm to 30mm, providing complete coverage with no skipped sizes. Each socket is approximately 75 percent shorter than standard shallow impact sockets, allowing access to extremely tight spaces. Designed for 1/2 inch drive impact tools, the sockets are constructed from durable Chrome Molybdenum steel for long-lasting strength. A 22mm outside hex profile allows wrench assistance when a ratchet cannot fit. Ideal for automotive and heavy-duty applications, the set includes a simple lifetime warranty for added confidence.
