Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

You can weld these nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

Projections on the base concentrate the weld and provide room for heat to dissipate.

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

Weld these nuts to uncoated steel surfaces.

A smooth base provides more contact with the mating surface than weld nuts with projections.

Weld these nuts to stainless steel surfaces.

Threads float inside the retainer so you can install a bolt at a slight angle to align with off center parts.

About half the strength of medium-strength steel coupling nuts, these metric nuts are for light duty fastening applications.
