US PRO 3822 21mm Impact Socket 1/2 Inch Drive 6 Point Euro Style Box of 10

When you’re leaning into suspension bolts, chassis fixings, or those stubborn fasteners that have seen too many winters, you need a socket that bites cleanly and stays dependable under load. The US PRO 3822 21mm Impact Socket is built for that everyday, high-torque reality.

Forged from strengthened 50 chrome vanadium steel, this Euro style 6 point socket is hardened for durability and finished in black phosphate to help resist corrosion and workshop wear. The 6 point profile grips the flats of the fastener more securely to help reduce rounding, while the 38mm length keeps it compact and practical for general servicing. Supplied as a box of 10 on hangers, it’s ideal for shared tool bays, maintenance teams, and service vans where having spares avoids downtime.
