US PRO 3820 18mm Impact Socket 1/2 Inch Drive 6 Point Euro Style Box of 10

When a fastener has been heat-cycled, road-salted, or hammered tight over time, the socket you choose matters. The US PRO 3820 18mm Impact Socket is built for those real workshop moments, where you need clean engagement, controlled force, and a tool that keeps its shape under repeated use.

This Euro style 6 point impact socket is forged from strengthened 50 chrome vanadium steel and hardened to HRC 48 for durability. The 6 point profile helps reduce rounding by loading the flats more securely, while the black phosphate finish adds protection against corrosion and everyday wear. At 38mm long, it’s a practical standard-length impact socket for frequent servicing tasks. Supplied as a box of 10 on hangers, it’s ideal for tool control, shared benches, and service vans where spares keep jobs moving.
