Impact Socket 12-Point 18mm 1/2-Inch Drive, Chrome-Molybdenum Construction

Brief Overview

This 18mm impact socket is purpose-built for pneumatic impact wrenches and delivers the durability required in high-volume shop environments. The 12-point design balances accessibility with reduced rounding risk, while the chrome-molybdenum construction absorbs the shock and torque demands of impact tool operation. Whether you're stocking a general repair facility or supplying specialty technicians, this socket pairs seamlessly with complementary sizes like the smaller 12-point socket options or the larger impact socket formats to build a complete drive system.
