US PRO 3821 19mm Impact Socket 1/2 Inch Drive 6 Point Euro Style Box of 10

In the workshop, 19mm is a size you don’t “own”, you use. It’s on suspension bolts, chassis fixings, and all the fasteners that don’t care how late the job is running. The US PRO 3821 is built for those everyday hits, where a standard socket isn’t the right bet.

This 6 point Euro style impact socket is forged from strengthened 50 chrome vanadium steel and finished in black phosphate to help resist corrosion and wear. The 6 point profile loads the flats more securely to help reduce rounding under torque, while the compact 38mm length keeps it practical for tight-access work with 1/2 inch drive impact tools, breaker bars, and ratchets. Supplied as a box of 10 on hangers, it’s ideal for busy garages, multi-user benches, and tool control setups where spares keep work moving.
