Yes, the threads were clean and not damaged when I changed the filter each time. I had the same thought about the tightening the filter once it cools down and later expanding as it heats up. I don't know if it matters. I do know that it made no difference in the removal, warm engine or dead cold that filter on there. Once the seal was broken the filter spun easily. I am reluctant to tighten this new filter more should I see a small oil drio from the filter.
