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.
Nuts that meet ASME B1.1 comply with specifications for dimensional standards.
Steel Hex Weld Nuts
With three weld points, these hex weld nuts create a secure hold on steel surfaces. 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 on thick pieces of metal. Made of uncoated steel, they require minimal prep for welding to uncoated steel surfaces. All have a collar pilot to guide the nut into the hole and hold it in place while welding. This also protects the threads from weld spatter.
All nuts meet ASME B1.1 and comply with specifications for dimensional standards.
Tube-End Weld Nuts
Weld these nuts to round uncoated metal tubes to attach threaded parts, such as rod ends. Also known as tube adapters and weldable threaded tube ends.
