    Hammer-In Threaded Inserts for Softwood

    Image of Product. Bottom orientation. Threaded Inserts. Hammer-In Threaded Inserts for Softwood.
    Barbs on these inserts dig into softwood for a secure hold. The flange keeps them from being pulled through the material and adds a load-bearing surface. They’re good for light duty assemblies that don't need the precise fit of tapping inserts, such as furniture and shop fixtures. Hammer inserts into a drilled hole to install. The installed length includes the flange.
    Zinc Alloy—Soft enough to cut into wood without splitting it, these inserts also resist occasional moisture.
