I see what you're saying and agree. Using the proper tools to measure the diameter/threads is a good idea. Simply comparing them side to side is also a way to determine what they have. Like SAE fasteners, the difference between fine and course threads are readily apparent when viewed next to each other. Also a tool to determine diameter would be beneficial if the person doesn't have access to a a caliper or diameter guage.
