ABSTRACT:
In order to manufacturer a tee nut by plastic working steps, a swollen portion is formed on a metal plate, a through hole is formed in the forward end surface of this swollen portion, and then the outer diameter and therewith the wall thickness of a forward end portion of the swollen portion is relatively reduced as compared to a base portion of the swollen portion. Then, the outer and inner diameters of the base portion are reduced while substantially maintaining its wall thickness. Thus, the forward end portion defines a relatively thin portion to be caulked, and the base portion defines a relatively thick female screw forming portion of the tee nut. Thus, it is possible to form a tee nut having a shaft with a uniform outer diameter and having a relatively thin forward end portion forming the portion to be caulked while the tee nut is held by the metal plate.
