    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.

    With an extended barrel and a round flange, these nuts distribute force evenly to prevent pull-through. The barrel is twice as long as standard round weld nuts, so more threads connect with your bolt for a great grip. You can weld these nuts in two orientations: on top of a flat surface or with the barrel sticking through the hole.
    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.
    Zinc-Plated Steel—A step up from plain steel, these nuts withstand occasional exposure to moisture. Weld them to uncoated steel surfaces. If MIG or TIG welding, grind the zinc plating off the part of the nut you intend to weld.

    With three projections and a short collar, weld these nuts under low-clearance areas without sacrificing strength. The projections concentrate heat away from the threads to prevent them from deforming and create consistent welds. To make welding easier, their collar pilot guides them into the hole and aligns them with the surface while also shielding the threads from weld spatter.

    Stainless Steel Adhesive-Ready Nuts

    Image of Product. Front orientation. Adhesive-Mount Nuts. Stainless Steel Adhesive-Ready Nuts.
    Add strong threads to material that’s too difficult to drill or too thin to grip a threaded insert. These nuts are ideal for brittle plastics or tough composites, such as acrylic or carbon fiber. They have large holes in the base so that adhesive or resin can flow through, spread out, and create an extra-strong hold. You can also mold them into the surface of your material. Made of 316 stainless steel, they resist corrosion from salt water and harsh chemicals.
    The base of these nuts acts like a flange, distributing pressure evenly across the mounting surface. The larger the base, the more that pressure is spread out; the smaller the base, the tighter the space these nuts can fit into. Taller nuts engage more of a screw’s threads than shorter nuts. Shorter nuts fit in low-clearance areas.

    Adhere or mold these nuts onto a surface without gunking up the threads—the closed end blocks out adhesive, resin, and debris. It also acts as a stop, preventing screws from penetrating your material. Use them to add strong threads to material that’s too difficult and brittle to drill, such as acrylic and carbon fiber. They’re also often used when the surface is too thin to grip a threaded insert. To create a secure bond, large holes in the base let adhesive and resin flow and spread along the joint. Made of 316 stainless steel, these nuts resist corrosion from salt water and harsh chemicals.

    Stainless Steel Narrow-Base Adhesive-Ready Nuts

    Image of Product. Bottom orientation. Adhesive-Mount Nuts. Stainless Steel Narrow-Base Adhesive-Ready Nuts.
    Add corrosion-resistant threads to channels, corners, and other tight spaces without drilling a hole. Glue these nuts on to thin surfaces and materials too hard and brittle to drill, such as acrylic and carbon fiber. Large holes in the base allow adhesive and resin to flow and spread along the joint for a good bond. You can mold them into plastics or composites. Made of 316 stainless steel, these nuts are excellent at resisting chemicals and salt water.
    The base of these nuts acts like a flange, distributing pressure evenly across the mounting surface. Larger bases spread the pressure over more surface for a strong bond, while smaller bases fit better in tight spaces.
