Abstract
A ball stud (12) with a relatively short grip length, adapted for use with a turbocharger, having a flexible flange (18) extending from a center of the ball stud (12). The flexible flange (18) is between a ball section (14) and a first shaft portion (20) adjacent to the flexible flange (18) and preferably a narrower threaded shaft portion (22) extending further from the ball section (14). The first shaft portion (20) may be tapered to fit in a complementary aperture (32) of a plate (30). The flexible flange (18) preferably includes a narrow circumference (24) adjacent to a center of the ball stud (12) with a circumferential lip (26) adapted to engage a plate (30). The flexible flange (18) allows subtle flex for thermal expansion and essentially changes a spring rate of the ball stud (12) to emulate a longer fastener.
