Units and Core Parameters
Threads are described by four numbers that all have to match for a bolt and nut to fit together: thread diameter (the nominal size, e.g. M8), pitch (distance between threads), flank angle (thread shape, usually 60°), and truncation (how flat the crest and root are).
Target Matching
Pick a bolt or nut as a Match Target and its thread dimensions are copied over automatically, so the two are guaranteed to fit together.
