Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts.

Lock Nuts/ Thin Nuts

A locknut/ half nut/ locking nut is tightened behind another nut as an extra precaution to prevent a fastening from loosening due to vibrations and/ or torque. These nuts are approximately half the thickness of a full nut.
