The document provides a comprehensive overview of mechanical fasteners, including their definitions and classifications such as threaded and non-threaded options. It discusses various types of fasteners like nuts, bolts, and screws, along with their applications in fastening mechanisms. Key concepts include the differences between detachable and non-detachable fasteners, as well as thread terminology.

9. A nut is a type of hardware fasteners with a threaded hole.
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.
A washer is a thin plate typically disk-shaped with a hole that
is normally used to distribute the load of a threaded fastener.
