Nut & bolts
1.
2. 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.
3. Carbon steel and Alloy steel material used for Nut &
Bolt manufacturing.
Nut mfg by Blanking and Threading. Bolt by forging
and threading.
