3/8″ is the diameter of the bolt shank… the non threaded part that the threads are cut into. Then in 3/8″ the coarse thread is 16 threads per inch and for fine thread it is 24 threads per inch.
What do bolt size numbers mean?
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.

Are M10 and 3/8 the same?
That said, they are very close, the 3/8″ bolt is about 0.019″ smaller and the pitch’s are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..
What size bolt should I use?
A typical rule of thumb . . . Use a bolt diameter that is 1.5 – 2.5 times (up to three times) the thickness of the thinner material you are bolting together. So, for 1/8″ material, a 1/4″ diameter is often a good bolt choice. For 1/4″ thick material, perhaps a 3/8″ or 1/2″ bolt.
What does M12 mean?
6. Those are metric screw dimensions. M10 means a 10 millimeter outer diameter for the bolt or whatever piece it is; M12 means 12 millimeters. The part after the ‘x’ is the pitch — how many mm a thread is wide. To figure out which you have, you can measure the existing part with calipers and a thread gauge.
How do you identify bolt grades?
You can usually figure out the grade, or strength, of a bolt by looking at the markings on its head. English bolts (U.S.S. or S.A.E) are categorized by grade, from grade 2 to grade 8, where the grade represents inch strength. The higher the grade, the stronger the bolt.
