ABSTRACT:
In interconnecting construction between a bolt and a mounting plate such as a shell of a brake booster is disclosed. A sealing, annular projection is formed in an end face of a bolt head so as to surround a bolt shank which is formed with a serration. Both the annular projection and the serration are caused to bite into the opposite surfaces of the mounting plate, whereby an excellent sealing effect and locking action against rotation are simultaneously achieved.
