A coaxial cable connector generally includes a connector body, a nut rotatably coupled to the connector body, a post disposed in the connector body and a biasing element acting between the post and the nut. The nut has an internal thread for engagement with an external thread of a mating connector. The internal thread of the nut and the external thread of the mating connector can be mismatched, wherein an interference fit is created therebetween upon connection of the nut to the mating connector. Also, the post can have a forward flanged base portion disposed within the axial length of the internally threaded surface of the nut, which, together with the biasing element, provides a constant force between the post and the nut.
