ABSTRACT:
The present invention provides a T-nut having an improved structure capable of preventing a liquid, such as oil or paint, from entering into the inside of a shank of the T-nut. The T-nut has a tubular shank having a first end and a second end located on the other side of the first end, and a flange extending outward from the first end of the shank. The shank and flange are made of metal material and formed integrally. At least a part of the shank is formed as an internally threaded portion. The T-nut comprises a bottom-sealing member located adjacent to the first end of the shank to seal the bottom of the tubular shank.
