    Black-Oxide Steel—Create a finished look with a dark, matte coating. These nuts offer minimal corrosion resistance, so they're best for dry environments.
    18-8 Stainless Steel—Stainless steel nuts have excellent corrosion resistance. They are a good choice for use with stainless steel parts or in EDM applications.
    Fully Threaded—Fully threaded nuts allow a stud to extend beyond the bottom of the nut.
    Partially Threaded—Partially threaded nuts keep studs from traveling past the bottom of the nut and damaging your table.

    Tee-Nut Threaded Inserts for Wood

    Image of Product. Front orientation. Threaded Inserts. Tee-Nut Threaded Inserts for Wood.
    A four-pronged flange resists twisting in hardwood and softwood. These inserts are good for light duty assemblies that don't need the precise fit of tapping inserts. Hammer them into a drilled hole to install. The installed length includes the flange.
    Steel—Best for dry environments since moisture will cause these inserts to rust.
    Black-Oxide Steel—These inserts are often chosen for the dark, matte appearance. They're best for dry environments since they can rust when exposed to moisture.
    Zinc-Plated Steel—A step up from plain steel, the plating withstands occasional exposure to moisture.

    Screw-Mount Nuts

    Style A

    Style B

    These screw-mount nuts have three mounting holes to accept screws and rivets. Insert the barrel through a hole or fasten the base with the barrel facing upward for use with thin materials. Since the base is flanged, it helps spread out the load. A larger base means more room for weight to spread. The longer the barrel, the more thread engagement with your screw.
    Style B—Style B nuts can also be welded for a stronger, permanent hold. The three projections on their base concentrate your weld and create room for heat to dissipate, protecting threads from deforming.

    Drop-In T-Slot Nuts

    Mount clamps and other fixtures to machine tool tables anywhere along the length of your T-slot track. These nuts install from the top and secure with a quarter turn, so you don’t have to slide them down the track’s length. They’re often paired with setup studs for adjustable fixtures. Also known as quarter-turn T-slot nuts.

    Rectangular Weld Nuts

    Image of Product. Bottom orientation. Weld Nuts. Rectangular Weld Nuts.
    These nuts add permanent threads in narrow spaces such as channels. With a slim footprint, they fit where round weld nuts can’t. Plus, their barrel is twice as long as low-profile barrels, so more threads connect with your bolt for a secure hold. You can weld these nuts in two orientations: on top of a flat surface or with the barrel sticking through a 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.
    Number of Projections—Weld these nuts on top of metal—the projections on the bottom will fuse to the surface. More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

    Square Weld Nuts

    Image of Product. Bottom orientation. Weld Nuts. Square Weld Nuts.
    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.

    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.
    Number of Projections—Weld these nuts on top of metal—the projections on the bottom will fuse to the surface. More projections lead to more consistent welds by concentrating heat and protecting the threads from deforming.

    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.

    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.
