ABSTRACT:
In order to prevent a flange of a tee nut which is moved along a feed track from overlapping with that of another tee nut so that the tee nut can be smoothly fed along the feed track, the flange is an octagon having linear sides coupling paired the two pawls of each of two pairs of pawls with each other. To firmly and semi-permanently fix the tee nut in an object, a relatively thin-walled flarable or splayable portion is formed on an end of a shaft away from the flange. A female screw forming portion is provided on a portion of the shaft excluding the flarable or splayable portion. When this tee unit is mounted on the object, the pawls bite into the object and the flarable or splayable portion is flared or splayed to form a flared or splayed rim.
