Install threads in channels and other tight spaces where round-base weld nuts won’t fit. These steel weld nuts stand up to high torque and pull force better than rivet and press-fit nuts, making them the strongest way to add permanent threads to sheet metal. They can also be welded onto thick metals and molded into plastic surfaces. In plastic, their rectangular shape keeps them from twisting.

A base that’s flat on both sides allows these nuts to be welded in two orientations: either flush on a flat surface or with the barrel sticking through a hole. Twice as long as those on low-profile weld nuts, the standard-length barrel creates greater thread engagement.

Plain steel nuts can be welded to uncoated steel with less prep than zinc-plated steel nuts.

Zinc-plated steel nuts resist rusting in wet environments better than plain steel nuts. Weld them to uncoated steel surfaces, but keep in mind this will take extra prep, such as grinding off some of the zinc plating.

A smooth base provides more contact with the mating surface than weld nuts with projections. Both sides of the weld nut base are flat, so it can be welded flush to a surface or with the barrel through the hole. Use them to add strong, permanent threads to uncoated steel surfaces. Its barrel is twice as long as low-profile weld nuts for added thread engagement. Because they’re welded on, they can stand up to more torque and pull force than rivet nuts.

Uncoated steel weld nuts can be welded on with minimal preparation.

Zinc-plated steel weld nuts are corrosion resistant in wet environments. They require some preparation before welding, such as grinding off the plating from the part of the nut you intend to weld.

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.

Threads float inside the retainer so you can install a bolt at a slight angle to align with off-center parts. Weld these nuts to metal surfaces for a strong, permanent hold. They stand up to high torque and pulling force better than rivet nuts.

For the strongest threads, choose steel nuts. Nuts with a steel retainer should be welded to uncoated steel surfaces.
