For more on marking an answer as the "Best Answer", please visit our FAQ.It all depends on the thread. As Tony says, 3/8"AF would be American, measuring across the flats ie the width of the bolt head.
If it's old BSF (British Standard Fine ) or BSW (British Standard Whitworth) it'll be a measurement of the threads, so the head would be something else entirely. Thank goodness those old things are largely gone now.
.... and don't get started on ANC (American National Coarse) and ANF (A N Fine)
With metric, 6mm would be the diameter of the shaft of the bolt ......
... don't ask ;o(

Try buying wood screws in metric, they are a nonsense, not like the old 1" eights, or 2" black japped 6's, not confusing at all. ha ha.
who thinks these up???
Its like the screw heads, there are posidrive, cross head,phillips, slotted phillips, torx etc. different screwdrivers needed for each one.
I bought some decking screws, they gave a free screwdriver bit with them. good job they did, nothing on this earth will fit the screws, and the screwdriver bit will fit nothing else in the universe.
Good night,
