    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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.
    Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these inserts won't degrade when exposed to harsh weather, salt water, and most chemicals.

    Split-Preventing Tee-Nut Threaded Inserts for Hardwood

    Prongs or barbs create a secure fit that won't split hardwood. To install these inserts, hammer them into a drilled hole. The installed length includes the flange.
    Pronged Secured—With just three short prongs, these inserts are less likely to damage dense wood than other tee nut inserts.
    Barbed Secured—The ridged barrel makes these inserts even less likely to split hardwood than pronged inserts. They're often used in wood that has been cut across the growth rings.
    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.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Create strong threads in wood and plastic that won’t get clogged during finishing processes. These inserts have a silicone plug that blocks out paint, coatings, and debris—and won’t melt when exposed to heat. The flange has four prongs that grip the surrounding material to help prevent twisting.
    For wood, install the inserts in a drilled hole at any time. For plastic, install them before injection molding. Once finishing is complete, pop the plug out by threading your fastener through the insert or just peel it off.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals. Since they’re lead-free, they can be safely recycled.

    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.
