ITEM NAME:120pcs Threaded Nuts Entry Thread Drive Nut M3 M4 M5 M6 M8 FT Description: A T-nut is a type of nut used to fasten a piece of wood, particles, or composites, leaving a flush surface. It has a long, thin body and a flange at one end, which resembles a T-profile. The T-nut flanges have tines that dig into a wood workpiece when the bolt is tightened from the opposite side of the piece to provide better retention. Properties: These four-pronged T-nuts are made of carbon steel and coated with zinc for rust and corrosion protection. These nuts are used to provide a robust, reliable and easy-to-install threaded sleeve in wood and chipboard. Convenient to use, just tap these nuts into a hole of appropriate size, and the pins hold them in place. These four prongs prevent the T-nut from rotating when inserted into pieces of wood and tightened. This set contains 5 nuts of various sizes, which are supplied in a resealable sorted carton to facilitate transportation and storage.
