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.

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.

A smooth base provides more contact with the mating surface than weld nuts with projections. Both sides of the base are flat, so these metric weld nuts 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. Their 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.

Add corrosion-resistant threads to stainless steel sheets, even in spaces with low clearance. These nuts have a short collar to fit in confined spaces. To make welding easier, their collar pilot guides them into the hole and aligns them with the surface. It also shields the threads from weld spatter. The round base acts as a flange to evenly distribute force, while the projections concentrate your weld. This makes room for heat to dissipate, protecting the threads from deforming. 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. You can also weld them to thick metal surfaces.

Add strong threads to material that’s too difficult to drill or too thin to grip a threaded insert. These nuts are ideal for brittle plastics or tough composites, such as acrylic or carbon fiber. They have large holes in the base so that adhesive or resin can flow through, spread out, and create an extra-strong hold. You can also mold them into the surface of your material. Made of 316 stainless steel, they resist corrosion from salt water and harsh chemicals.

The base of these nuts acts like a flange, distributing pressure evenly across the mounting surface. The larger the base, the more that pressure is spread out; the smaller the base, the tighter the space these nuts can fit into. Taller nuts engage more of a screw’s threads than shorter nuts. Shorter nuts fit in low-clearance areas.

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. They have large holes in the base so that adhesive or resin can flow through, spread out, and create an extra-strong hold. They can also be molded into plastics or composites. A zinc plating helps keep these nuts from rusting in wet environments.

Adhere or mold these nuts onto a surface without gunking up the threads—the closed end blocks out adhesive, resin, and debris. It also acts as a stop, preventing screws from penetrating your material. Use them to add strong threads to material that’s too difficult and brittle to drill, such as acrylic and carbon fiber. They’re also often used when the surface is too thin to grip a threaded insert. To create a secure bond, large holes in the base let adhesive and resin flow and spread along the joint.
