A coaxial cable connector includes a nut housing having a rearward cable receiving end and a forward end opposite said rearward end, a front nut assembly coupled to the forward end of the nut housing, and a conductive metal tubular insert shaft supported within the nut housing or the front nut assembly. The front nut assembly includes an entry body housing and a conductive terminal pin extending from a forward end of the front nut assembly, and the conductive metal tubular insert shaft has a rearward end portion. A nonconductive plastic tubular support sleeve has a forward end portion coupled with the rearward end portion of the conductive metal tubular insert shaft, a tubular gripping ferrule radially surrounds the metal insert shaft and the plastic support sleeve, and a tubular outer sleeve radially surrounds at least a portion of said gripping ferrule. The gripping ferrule and the tubular outer sleeve are configured to be moved relative to one another in an axial direction such that the gripping ferrule and the tubular outer sleeve are configured to engage one another, thereby causing the gripping ferrule to radially compress around the conductive metal tubular insert shaft and the nonconductive plastic tubular support sleeve.
