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.
