According to embodiments of the invention, an electrical connector for use with an electrical conductor having a terminal end includes a connector body and a stud member. The connector body includes a conductor engagement section and a stud mounting section. The conductor engagement section is configured to receive the terminal end of the conductor to mechanically and electrically connect the conductor to the connector. The stud mounting section includes a socket bore including a tapered bore section. The stud member includes an elongate stud section extending to a free end, and a tapered insertion section. The tapered insert section is received in the tapered bore section. The tapered insert section includes an internal cavity defined therein to permit deformation of the tapered insert section as the tapered insert section is forced into the tapered bore section.
