    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.

    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.

    Weld Locknuts

    Prevent screws from backing out under heavy vibration. These nuts have distorted threads that grip screws tightly. Three evenly spaced projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. These nuts also have a collar pilot that guides the nut into the hole, holds it in place while welding, and protects the threads from weld spatter.
    Use Grade 2 or Class 6 screws to avoid stripping threads during installation. Distorted threads require high torque for fastening and unfastening, so you may need an impact wrench to remove screws.
