Fewer prongs than other tee nut inserts reduce the risk of splitting hardwood—these inserts have three short prongs. Hammer them into a drilled hole to install. Installed length includes the flange.

Unfinished steel inserts are best for dry environments, since moisture will cause them to rust. They are ready for painting.

Zinc-plated steel inserts are mildly corrosion resistant in wet environments.

Black-oxide steel inserts have a dark surface color and are mildly corrosion resistant in dry environments.

With only three prongs—fewer than our standard tee nut inserts—these inserts are less likely to split hardwood. They’re made of 18-8 stainless steel, so they stand up to mild chemicals and water better than steel inserts. Hammer them into a drilled hole to add strong, reusable threads. Use them in place of wood screws, which wear out wood with repeated use. The flange keeps them from being pulled through the hole and helps distribute loads evenly, protecting the wood. Installed length includes the flange.
