    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.
