Abstract
A monolayer metal gasket is disclosed in which variations in radial width of a core plate around bore apertures help regulate a sealing stress throughout around bore apertures. The monolayer metal gasket is comprised of a core plate extending around the bore apertures and a perimetral member surrounding throughout the core plate. The core plate is varied in its own radial width circumferentially of every bore aperture in such a manner as to become narrow at areas neighboring tightening holes while wide at the remainder. In this monolayer metal gasket, the sealing stress around the bore apertures may be compensated in part by varying the radial width of the core plate circumferentially of every bore aperture.
