Square Weld Nuts
Square weld nuts have more weld points than hex weld nuts for a stronger hold. Weld them on flat uncoated steel surfaces. All have a collar pilot that assists alignment and prevents welding spatter from getting into threads.
Nuts that meet ASME B1.1 comply with specifications for dimensional standards.
