20mm 1/2" Drive Deep Impact Socket – 6-Point CR-MO Steel

20mm Deep Impact Socket for 1/2" Drive

Engineered for heavy‑duty torque, this 27mm deep impact socket is designed to pair with standard 1/2" drive impact wrenches and ratchets. Crafted from Chrome Molybdenum (CR‑MO) steel and heat‑treated for maximum strength and impact resistance, it stands up to repeated hammer blows without deforming—a reliable choice for the toughest fasteners in demanding environments.

The deep profile reaches recessed bolts and extended studs without adapters, and the 6‑point design increases contact area for a secure grip, helping to reduce fastener rounding in high‑torque situations.

The black phosphate coating adds corrosion resistance, extending tool life in harsh workshop conditions. Fully compatible with standard 1/2" drive impact wrenches and ratchets, it integrates smoothly into professional toolsets. Meets or exceeds ANSI/ASME standards.
