A metal injection molding process for manufacturing a MIM article with a final main body and a final threaded hole defined in the final main body, is provided. The metal injection molding process includes forming a green MIM article including a green body, the green body having the same shape as, but larger than the final main body; tapping the green body to define a green threaded hole in the green body, the green threaded hole having the same shape, but larger than the final threaded hole; debinding the green MIM article to remove the plastic binders from between the metal powders; and sintering the green MIM article to form the MIM article by shrinking the green body to form the final main body and shrinking the green threaded hole to form the final threaded hole.
