A stud for connecting a first housing with a second housing. The stud has a cylindrical body with a head on a first end thereof. The head has a face with an irregular surface that extends from a guide surface to the periphery of the head. The guide surface extends through an opening in the first housing until the irregular surface engages the housing adjacent the opening. An orbital rotating tool engages the guide surface causing the guide surface to flare and engage the housing when a constant pressure is applied to the head. Thereafter, the material adjacent the opening flows into the irregular surface to seal the opening while preventing the stud from rotating when a torque is applied to the cylindrical body.
