Thread Checker Basics - plus a tip to match threads without one!

The basics of thread checkers - a simple tool to determine what size (diameter and thread pitch) a given screw/bolt/nut is.

Plus a tip to quickly figure out if two screws/bolts match whether you have this tool or not (more useful for when you don't care what the screw size is, you just want to know if two random screws are the same)!

How do you use the female end on a fixed bolt when you cannot spin the whole thing much ???

Having both 8mm and 5/16" bolt for replacement. Size appears correct, but the threads on both are too tight together compared to my original bolt. What to do next? Thanks
