A process for forming a fastener for use in a D-Sub electrical connector to enable the connector to fixedly connect with a mated connector by threadedly engaging a bolt with the fastener, comprising the following steps: stamping a first metallic plate to have a first face with a number of parallel V-cuts therein, a second opposite face with an elongate flange, and a number of keys above the flange; bending the first metallic plate to obtain a sleeve with the V-cuts forming an internal thread in the sleeve, a circular flange at a lower edge of a peripheral perimeter of the sleeve, and a number of keys above the circular flange; stamping a second metallic plate to form a base having a first hole, a circular protrusion projecting into the hole, and a number keyways in the protrusion; and assembling the sleeve to the base by extending the sleeve through the hole to reach a position in which the sleeve has an interferential engagement with the protrusion, the keys are fittingly received in the keyways, and the circular flange is received in the first hole by an interferential fit.
