    Add permanent threads to thin metal with our go-to weld nuts. Unlike press-fit and rivet nuts, these nuts fuse to the base metal, so they won’t twist and pull out. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. 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. You can also install them on thick pieces of metal.
    Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.
    18-8 Stainless Steel—Suitable for outdoor use, these nuts resist rust from water and mild chemicals. Weld them to stainless steel surfaces.
    Grade 2 Titanium—The best choice when you need a high strength-to-weight ratio, these nuts are 40% lighter than steel nuts. They’re also our most corrosion-resistant weld nuts, standing up to salt water, strong acids, and other harsh chemicals. Weld them to titanium surfaces.

    With four symmetrical projections, these nuts create the strongest hold in our offering. Unlike rectangular weld nuts, each projection is equidistant from the threads, so welds wrap evenly for extra strength and twist resistance. Projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. All nuts have a collar pilot that guides them into the hole, holds them in place while welding, and protects the threads from weld spatter.
    Steel—Best for dry environments since moisture will cause them to rust. Made of uncoated steel, these nuts require minimal prep. Weld them to uncoated steel surfaces.
