What is Nut?

Nut is a type of fastener with a threaded hole, always used with bolts to fasten two or more objects by threads. The nut and bolt are kept together by their threads’ friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.
