Tongue-Tite

The original, and still the best. Tongue-Tite® is the perfect solution for installing tongue-and-groove flooring thanks to its neat, near-hidden head.
The screw is inserted into the tongue at a 30o to 45o angle, securing the board with the tiny head sinking into the tongue and allowing the next board to slot cleanly into place. No glue. No nails. No mess, just a solid, lasting fix.
