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.
