Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold. A collar pilot assists alignment and prevents welding spatter from getting into threads.
All nuts meet ASME B1.1 and comply with specifications for dimensional standards.

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.

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.
