    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.

    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.

    Weld in place for greater rigidity and strength than other studs. These studs have a wide base that distributes the load and projections that concentrate the weld. Length listed is overall length.
    Steel—Without a finish, these studs require minimal prep work before welding. After installation, you can paint them for a finished look.
    Below-Head Projection—Choose these studs for a strong hold that uses the full strength of the fastener. Pass through a hole and weld them in place.
    Above-Head Projection—Weld the head directly to the surface of the material for a smooth appearance.
