Meanwhile International Standard specifies the characteristics of hexagon head bolts with threads from M1,6 up to and including M64. Of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10d or 150 mm, whichever is the shorter. And product grade B for threads over M24 or nominal lengths over 10d. Bolts are often used to make a bolted joint. Furthermore this is a combination of the nut applying an axial clamping force and also the shank of the bolt acting as a dowel.Pinning the joint against sideways shear forces. For this reason, many bolts have a plain unthreaded shank (called the grip length) as this makes for a better, stronger dowel. Whereas the presence of the unthreaded shank has often been given as characteristic of bolts vs. screws, but this is incidental to its use, rather than defining.
