Astro Pneumatic Tool 78244 11-Piece 1/2 in Drive Nano Pinless Universal Impact Sockets - Metric

Overview

The Astro Pneumatic Tool 78244 set delivers a compact, high‑performing solution for metric fasteners. Built from chromium‑molybdenum with a lifetime warranty, these sockets are engineered to withstand demanding impact work while keeping your toolkit organized with an aluminum holder. A pinless, universal head design unlocks full 360° movement, letting the socket angle and rotate to reach stubborn fasteners in tight spaces. The hex ball swivel design helps transfer impact energy more directly to the bolt, distributing load for improved durability during repeated use.
