US PRO INDUSTRIAL 1/2"" Drive Impact Hex Bit Socket - 19mm - 78mm

The socket is manufactured from professional-grade Chrome Molybdenum Steel (Cr-Mo).

The steel is hardened to HRC50-53.

It is specifically designed for VAG hub nut bolts.

Yes, it features a 1/2" drive and can be used with any compatible 1/2" drive ratchet, bar, or extension.

The total length of the socket is 78mm.

The black phosphate finish provides protection against corrosion and abrasion. While durable, heavy use or harsh chemical exposure could eventually cause wear.

Yes, it is an impact socket designed for use with impact wrenches and other high-torque tools.

Ensure you are using the correct 19mm socket for a 19mm hex bolt. Check for debris within the socket or on the bolt head. Verify that the bolt is indeed a hex type and not another head style.

Confirm you are using the correct size socket. Ensure the socket is fully seated on the bolt head before applying torque. Use a higher torque impact tool if necessary to break loose stubborn fasteners, rather than prolonged high torque on a slightly ill-fitting socket.

Wipe the tool dry immediately and store it in a dry location. For minor surface rust, a light application of penetrating oil and a soft brush may help. Ensure the black phosphate finish is intact; if significantly damaged, reapply a protective coating or consider replacement.

Ensure your drive tool is indeed a 1/2" drive. Check the drive square on both the socket and the tool for any damage or obstructions that might prevent a proper connection.
