Abstract: There is provided a system and method for temporarily locking a wellhead component while cementing it in place within a mineral extraction system. As cement is pumped into the wellhead, its temperature may be increased, leading to thermal expansion of the cement and movement of wellhead components. Disclosed embodiments include a hold-down ring configured to cooperate with tie-down screws to temporarily lock a running tool in place within the wellhead during cementing. In another embodiment, the tie-down screws may cooperate directly with the running tool. The locked running tool then blocks other wellhead components, such as a hanger run into the wellhead by the running tool, from upward axial movement due to thermal expansion of the cement during the cementing process. After the hanger is cemented in place, the running tool may be unlocked and retrieved from the wellhead.
