Brief Overview

This 3/8-inch drive long hand socket delivers extended reach for fasteners recessed in tight engine bays, around obstructions, and in assembly work where standard sockets fall short. The 12-point profile engages fasteners at multiple angles, reducing cam-out risk and protecting bolt corners—critical for repeat fastening cycles in professional shops. A full range from 8mm to 24mm covers most metric fastener applications in automotive service. Stock complementary tools like deep-reach socket variants to maximize accessibility across different fastening scenarios.
