A weld nut has a base panel and a nut. The base panel has a through hole formed therethrough and multiple weld points formed on a bottom thereof. The nut is mounted securely in the through hole in the base panel and has a nut body, a connecting section and a threaded hole. The connecting section is formed on and protrudes axially from the nut body and is mounted securely in the through hole. The threaded hole is formed through the nut body and the connecting section to screw with a bolt. The base panel has a lower carbon content and has an excellent weldability to make the weld points easy to be welded on a workpiece. The nut has a higher carbon content and has an enhanced hardness to prevent deformation resulting from an axial force.
