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.

With a slim base and a short barrel, these corrosion-resistant weld nuts fit in tight spaces and in low-clearance areas.

Install threads in channels and other tight spaces where round-base weld nuts won’t fit.

Slim at the base, these weld nuts fit in channels and other spaces too tight for round-base weld nuts. Weld them to stainless steel surfaces to add strong, permanent threads that resist corroding from chemicals.

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.

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.

Add strong threads to material that you can't drill or that's too thin to grip a threaded insert. These nuts are ideal for brittle plastics or tough composites, such as acrylic or carbon fiber.
