ABSTRACT:
A steel laminate gasket comprises a first plate having at least one first hole, a second plate situated adjacent to the first plate, and at least one depression formed either on the first plate or the second plate and extending toward the other. The second plate is provided with at least one second hole and a bead extending around the second hole. The bead extends substantially perpendicularly to a horizontal plate of the second plate toward the first plate to abut against the first plate. Height of the depression is substantially the same as or slightly less than that of the bead so that when the first and second plates are connected together by a spot welding at the depression, the first and second plates are maintained substantially parallel to each other.
