    Weld Anchors for Concrete

    Image of Product. Front orientation. Contains Annotated. Anchors. Weld Anchors for Concrete.
    Also known as Nelson studs, these anchors strengthen the connection between steel framing and concrete. Weld them to the framing to enhance adhesion and resist shear forces. Their heads ensure secure embedding when wet concrete is poured. A ferrule is included if you choose to weld with a stud welder. Designed for permanent installations, you'd have to cut these anchors out to remove them.
    Steel—Best for dry environments since moisture will cause these anchors to rust.

    Pass these pins through a mounting hole and spot weld the head to the surface for greater rigidity and strength than other pins.
    Carbon Steel—Carbon steel pins have good strength.
    18-8 Stainless Steel—18-8 stainless steel pins offer a balance of strength and corrosion resistance. They may be mildly magnetic. Pins are passivated for added protection against corrosion and oxidation.

    Stud Welders

    Join threaded studs and pins to metal surfaces in milliseconds, forming bonds stronger than the studs themselves. Just load a stud into the gun, aim it against your base material, and pull the trigger to fuse the two together.
    Unlike drawn arc stud welders, our capacitor discharge systems work with metals less than a millimeter thick. They won’t leave fastener heads on the opposite side of the base material, so they’re often used for jobs requiring a clean-looking finish, such as attaching handles to high-end cookware. The one-sided welds are also preferred by the USDA for fabricating dairy tanks and other food-safe machinery – with no holes drilled, germs have nowhere to hide.

    • Suitable for steel and stainless steel base materials, as well as aluminum and brass
    • Also called fasteners
    Copper-Plated Steel—Copper-plated steel studs have good corrosion resistance.
    18-8 Stainless Steel—18-8 stainless steel studs are more corrosion resistant than copper-plated steel studs.
    Aluminum—Aluminum studs are more lightweight than steel or stainless steel studs. They’re nonmagnetic. In wet environments, they resist corrosion.
