Hmm it depends what the bolt is made of vs the housing.
IF the bolt material have higher coefficient of expansion it would get tighter, I think, when heated
somebody look up and compare all the common materials i.e. cast iron, steel, iron, derivatives of each, composites, and compare their coefficients of expansion and consider the most common materials that bolts are made of plus whatever is available (inconel for example) and let us know the results,
I am way to busy to do that atm
it raises an interesting question of bolt behavior at various expansion rates in our typical situations which I have never had an issue with (just use high quality fasteners and done) but if you want an actual answer thats a potential pathway
