(Problem to be solved by the invention) However, in such conventional bag nuts,
Since the welded part between the nut body and the cap body has a closed cross section and there is no air leakage, when attempting to attach a plating film to the surface by applying surface treatment such as plating to the welded nut body and cap body, There was a problem in that the adhesion of the film to the inner threaded portion and the workability of surface treatment were reduced.

In other words, when the nut body and the cap body are immersed in a plating liquid, the plating liquid does not immerse the inside of the nut body smoothly, and the coating on the inner threaded part, especially on the back side (cap body side), is damaged. The thickness may become very thin or uneven.
