What is the size of a metric bolt?
Metric bolts are referenced using “M” sizes, such as the M8 bolt size. The size of a metric bolt is specified using pitch, diameter, and length in millimeters. For example, in M8-1.0*20, the “M” means the Metric thread designation, the digit 8 refers to the Nominal diameter (in millimeters), 1.0 refers to the pitch, and 20 refers to the length.
How do I find the nominal thread length of inch-series bolts?
Per ASME B18.2.1, the nominal thread length of inch-series bolts can be found by: where L is the total bolt length and d nom is the nominal bolt diameter. The following table of hex bolt head dimensions was adapted from ASME B18.6.3, Table 29, “Dimensions of Plain (Unslotted) and Slotted Regular and Large Hex Head Screws.”

Is the diameter of a bolt the same as a nut?
But neither the external threads of the bolt nor the internal threads of the nut are exactly .500 in diameter. In fact, the bolt diameter is a little smaller and the nut diameter a little larger. But it is easier to specify the components by a single size designation since the bolt and nut are mating components.)
