Default RE: danger, 4 stroke prop coming off

Just thought of another issue that might be of interest to some. The last 2 to 3 threads on a bolt are not always the same diameter as the rest of the bolt, the threads taper at the end and do not grip as well as the rest of the bolt/propshaft. This feature allows the fastner to start threading more easily
