How many threads? Did you know that the first thread on a bolt takes a third of the load and the first three threads take 75% of the load? What's more, the first six threads take
the entire load. Numbers seven and above are under no load at all. Thus, if you've got six good threads, you have the equivalent of an infinitely long bolt.
