Steel Narrow-Base Weld Nuts

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.

Steel Low-Profile Narrow-Base Weld Nuts

With a slim base and a short barrel, these weld nuts fit in tight spaces, such as channels, and in low-clearance areas. 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. You can also install them onto thick pieces of metal. Made of plain steel, these nuts weld to flat, uncoated steel surfaces with minimal preparation.

Steel Offset-Barrel Narrow-Base Weld Nuts
![](/prerenderstable/mvPRE/contents/gfx/imagecache/945/94579a650p1-b01-digitall@halfx_636713279006540000.png?ver=imagenotfound)
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
![](/prerenderstable/mvPRE/contents/gfx/imagecache/945/94581a151p1-b01-digitall@halfx_637073481281957696.png?ver=imagenotfound)
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.
