What are nuts hardware used for?

Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads’ friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.

T-nuts are threaded steel inserts with prongs that insert claws into wood when they are tightened, and often work when wood screws fail. After a T-nut is installed, a common bolt is used to join corresponding parts together. If you can drill a hole, you can install a T-nut.

What was the screw used for?

Screws are used to hold things together as they pull or push the object. Screws may also be used for lifting heavy objects and to tighten things, like the vice in the image to the right.
