What are bolt sizes specified by?
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 can you tell the size of a bolt?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

How to Measure Socket Drive Size In the diagram above, the three key dimensions of a socket are labeled as Drive Hole, L, and S. L indicates the overall socket length. S indicates the target size of the nut, which determines which socket you’ll need. The size of the drive hole is determined by usage and torque demand.

What do the numbers mean on bolts?
The first number in each size is the nominal or root (minor) diameter (mm) and the second number is the thread pitch (mm). NOTE: Remember that the nominal bolt diameter is the measurement of the bolt diameter as taken from the bottom of the threads NOT the top (which would be major diameter).
How do you classify a bolt?
There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher number means the stronger the bolt.
