Steel Round-Base Weld Nuts
A smooth base provides more contact with the mating surface than weld nuts with projections. The base also acts as a flange to distribute the load. A long barrel ensures secure thread engagement.
Zinc-plated steel weld nuts are corrosion resistant in wet environments.

Round-Base Weld Nuts with Projections
Projections on the base concentrate the weld and provide room for heat to dissipate. Weld them to flat uncoated steel surfaces for a strong permanent hold. The round base acts as a flange to distribute the load. A long barrel ensures secure thread engagement.
