Nut is available in wide varieties of head designs. And these are designed according to the applications and end use to hold the various parts and engaged with the tools used to tighten them.
In Hexagonal head Nuts two tools are needed to fasten the Nuts one for the head and other for the Screw. Some Nut heads are designed to lock the bolt head in place, so that it does not rotate or move and only a tool is needed for the nut end to fasten them.
Nuts are often used to make a bolted/Stud joint. 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.
