Nuts (Fasteners)

Nuts are female threaded fasteners and companion to male threaded fasteners such as bolts, sometimes screws or any other components. Nuts are always used in conjunction to bolts with mating thread profile. Nuts and bolts are kept together by a combination of their threads friction a slight stretching of the bolt and compression of the parts to be held together. Most nut fasteners are 6 sided hexagon body design, which can be easily tigntened using a square or hex wrench.

Alike bolts, nuts can be hot forged or cold forged in stainless steel or other bolting grades with metric or imperial thread tapping. Nuts can also be machined from bar stock in case of unavailability of raw material, mass produce quantity or delivery time frame.
