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 create space for heat to dissipate, protecting the threads on these weld nuts from deforming. Made of 18-8 stainless steel, they withstand mild chemicals and can be used in wet and outdoor environments.

Projections on the base concentrate the weld and create space for heat to dissipate, protecting the threads on these steel weld nuts from deforming.

An offset barrel allows you to position threads near edges and corners.

To protect their threads from deforming, these steel nuts have a projection that concentrates your weld and creates room for heat to dissipate. An offset barrel lets you position threads near the edges and corners of uncoated steel sheets.

Projections on the base of these steel nuts concentrate your weld and create room for heat to dissipate, protecting threads from deforming. Weld them to uncoated steel channels and other tight spaces where round-base weld nuts won't fit.

Projections on the base of these nuts concentrate your weld and create room for heat to dissipate, protecting threads from deformation. Made of 18-8 stainless steel, these nuts withstand mild chemicals and can be used in wet and outdoor environments.

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.

Install corrosion-resistant threads in sheet metal to create a 90° joint.

These screw-mount nuts are often used to attach glides and levels to wood.
