I did a little more digging around and called a few parts departments to see if I could get a good answer. From the responses I received, I was told that it "appears" that these bolts are not one-time use (also known as "stretch bolts"). Stretch bolts, at least in BMW's, tend to be made of aluminum and are marked as "ASA" in the parts catalog. The ASA note was not present when these bolts were looked up so it appears that they can be re-used.
Although my research points to the conclusion these bolts can be re-used, I havent found anything completely definitive on the topic. Hopefully this will help someone in the future.
