Steel Offset-Barrel Narrow-Base Weld Nuts

An offset barrel allows you to position threads near edges and corners. Use these nuts to add strong, permanent threads to uncoated steel sheet metal or thick uncoated steel surfaces. With a narrow base, they fit in channels and other tight spaces where round-base nuts do not. They have a short barrel, so they fit in low-clearance areas, too. They stand up to more torque and pull force than rivet nuts.
Uncoated steel weld nuts require minimal preparation before welding.
Zinc-plated steel weld nuts resist corrosion 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.

Stainless Steel Offset-Barrel Narrow-Base Weld Nuts

These weld nuts have an offset barrel so you can position threads near edges and corners. Weld them to thin and thick stainless steel surfaces to add strong, permanent threads that won’t corrode from contact with chemicals. With a narrow base, they fit in channels and other tight spaces where round-base nuts do not. They have a low profile, so they fit in low-clearance areas, too. These nuts have a flat base that acts as a flange to distribute the load, so they stand up to greater torque and pull force than rivet nuts.

Steel Offset-Barrel Narrow-Base Weld Nuts with Projection

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. Narrow at the base, they fit into channels and other spaces too tight for round-base nuts. These 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 metal surfaces.

Stainless Steel Offset-Barrel Narrow-Base Weld Nuts with Projection

To protect their threads from deforming, these stainless 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 stainless steel sheets. Made of 18-8 stainless steel, these nuts withstand mild chemicals and can be used in wet and outdoor environments. Unlike round-base nuts, they have a narrow base to fit into channels and other tight spaces. They 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. You can also install them onto thick pieces of metal.
