The bolt body has three dimensions that are essential to any bolt size chart: bolt diameter and thread pitch. In standard bolt size charts, the thread pitch is the number of threads in one inch. In the metric system, it's the distance between two threads in millimeters. The thread pitch can be further classified as coarse, fine, and superfine.
