Metric Steel Hex Weld Nuts
The three weld points on these metric hex nuts create a secure hold on a steel surface. Weld them to sheet metal or thick steel surfaces to add strong, permanent threads. They stand up to high torque and pull force better than rivet nuts. Made of uncoated steel, there’s minimal prep required to weld them to uncoated steel surfaces. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter.

Metric Stainless Steel Hex Weld Nuts
You can weld these nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold. They have a collar pilot that assists alignment and prevents welding spatter from getting into threads.

Steel Screw-Locking Hex Weld Nuts
Irregularly shaped threads in these nuts form a tight grip, preventing screws from backing out in vibration-heavy environments. 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 threads to sheet metal. They can be welded onto thick metal surfaces, too. To protect their threads from deforming, these nuts have three projections that concentrate your weld and create room for heat to dissipate. A collar pilot guides the nut into the hole, lightly holds it in place during welding, and protects threads from spatter.
These nuts are designed for use with Grade 2 or Class 6 screws. Use screws that have a similar strength rating to avoid stripping threads during installation. Screw-locking threads require high torque for fastening and unfastening, so you may need an impact wrench to remove screws.

Square Weld Nuts
Square weld nuts have more weld points than hex nuts for a stronger hold. Use them to add strong, permanent threads to uncoated steel surfaces. They stand up to more torque and pulling force than rivet nuts. These fasteners are uncoated, so they require minimal preparation before welding. All have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter.

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.

Metric Aligning Weld Nuts
Threads float inside the retainer so you can install a bolt at a slight angle to align with off-center parts. Weld these nuts to metal surfaces for a strong permanent hold. They stand up to high torque and pulling force better than rivet nuts.

Stainless Steel Adhesive-Ready Nuts
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.
