A bolt gauge is divided into standard and metric sections. To measure screw size, we take its diameter. If there are four thread gaps in a one-inch length, the thread pitch would be 0.250 inches (one inch / 4 thread gaps = 0.250 inches). The first step in measuring the length is finding a surface to lay it down on an even surface.
