Tee nuts are pressed cylindrical nuts with a flat top and sharp prongs jutting 90 degrees down from the flat top and parallel to the cylindrical nut shaft. The cylindrical shaft is threaded internally. A captive nut, the tee nut allows one to put a threaded hole through wood, plywood, composite board, plaster, and other soft materials. The user can hammer the tee nut into a drilled hole in the material, then drill a screw through the threaded tee nut shaft into the material. Applications include furniture leg screw adjusters and internal wall mountings.
Stainless steel construction helps these tee nuts resist corrosion in demanding environments.
