(1)How is a hex bolt measured?
Length is measured from the point at which the head sits flat with the surface, to the tip of the threads.

Flat head screws are measured from the top of the head to the tip of the threads.

Hex bolts, or hex cap screws, are large bolts with a six-sided head (hexagonal) used to fasten wood to wood, or metal to wood.
