Abstract
A stud (24) and shell (10) arrangement wherein the shell (10) has openings (16 and 18) with a reinforcing ring (22) that is offset from a planar surface (20) and the stud (24) has a head (36) with a groove (38) located between the shank (30) and an arcuate section (40) adjacent its periphery (42). The ring (22) is located in the groove (38) and a cylindrical section (34) adjacent the head (36) is sheared to define a flange (35) that engages the ring (22) causing a portion thereof to flow around ribs (44), in the groove (38) and seal openings (16 and 18). Each of the ribs (44) has a first surface (52) which extends in a plane perpendicular to groove (38) and a second surface (56) which slope from an apex (54) toward the groove (38). The material from flange (35) engages the first surface (52) to resist torque that may be applied to both attach and remove a nut therefrom. The arcuate section (40) has sufficient area to uniformly distribute lateral forces that may be applied to the shaft (26) without effecting the seal.
