diameter Nominal diameter is a more of a label than a size For example a bolt and nut may be described as being 189 diameter 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

Screw Thread Design Fastenal

The following illustration demonstrates the pitch diameter allowances on a 3 4 10 bolt and nut The axial distance through which the fully formed threads of both the nut and bolt are in contact is called the length of thread engagement The depth of thread engagement is the distance the threads overlap in a radial direction
