Heat sink attachment components are provided comprising retention bolts with a coil spring captured between the head of the retention bolt and a retention lock flange of a retention lock. A portion of each retention bolt shaft is retained and in frictional engagement with socket bores of a mounting socket. A moderate interference fit between the retention lock and the retention bolt prevents unintended decoupling. While engaged, the compressed coil spring urges against the retention lock flange, with the retention lock flange in urging engagement with the heat dissipation side of a heat sink base, with the heat sink base in urging engagement with thermal interface material on the top of the microelectronic package. The urging engagement of the coil springs provide a constant bias for urging engagement between the components.
