ABSTRACT:
A steel laminate gasket of the invention is used for an internal combustion engine having at least one hole therein. The gasket comprises a first plate having at least one first hole and a first bead situated adjacent to the first hole to surround the same, and a second plate having at least one second hole and at least one second bead situated adjacent to the second hole to surround the same. The distance from the second hole to the second bead is different from that from the first hole to the first bead. When the first and second plates are assembled together, the first and second beads face against the second and first plates, respectively. When the gasket is tightened, the first and second beads form a plurality of corrugated beads at selected areas around the hole to securely seal the same.
