A bolt retainer mechanism in one layer of a multiple-layered steel (MLS) gasket, includes an aperture defining a radially inwardly extending tabs. In one embodiment, each tab is formed to define are inverted U-shaped tang positioned adjacent to, and in symmetrical registration with though axially spaced from, an associated mated aperture formed in a second layer of at least a two-layer gasket. Collectively, the plurality of tangs defines a circumscribed diameter slightly smaller than the diameter of the associated mated aperture, to assure retention of a bolt supported through the mated apertures for pre-assembly shipment. Preferably, the tangs in association with each of the mated apertures are formed of a spring metal adapted to provide radially inwardly directed forces against threaded shanks of associated bolts. To enhance effectiveness of bolt retention, the bolt- contacting portion of each U-shaped tab has an axial length greater than the axial thickness of the apertures.
