What is the difference between screws and nuts?
The screw is just a general term for fasteners, and it is just a daily spoken language. It includes: bolts, screws, and nuts. As long as there are threaded fasteners, bolts are a type of head and screw (cylinder with external thread). Fasteners need to cooperate with nuts to fasten and connect two parts with through holes. This form of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
The studs do not have heads, only a type of fasteners with external threads on both ends. When connecting, one end of it must be screwed into a part with an internal threaded hole, the other end passes through a part with a through hole, and then screw on the nut, even if the two parts are tightly connected to form a whole. This form of connection is called a stud connection and is also a detachable connection. It is mainly used in the occasions where one of the connected parts has a large thickness and requires a compact structure, or due to frequent disassembly, bolt connection is not suitable.
Screws are also a type of fastener composed of a head and a screw. They can be divided into three categories according to their uses: machine screws, set screws, and special purpose screws. The machine screw is mainly used for a tightening connection between a part with a threaded hole and a part with a through hole, which does not require a nut fit (this form of connection is called a screw connection and is also a detachable connection; it can also It is used with nuts to fasten the connection between two parts with through holes.) Set screws are mainly used to fix the relative position between two parts.
The nut has an internally threaded hole, and the shape is generally a flat hexagonal column, a flat square column or a flat cylinder. It is used to fasten and connect two parts with bolts, studs or machine screws to make it one. The whole screw is only a general term for fasteners, and it is a daily spoken language. It includes: bolts, screws, nuts, as long as there are threaded fasteners. The bolt is composed of the head and the screw (cylinder with external threads). A type of fastener needs to be matched with a nut to fasten two parts with through holes. This form of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Set screws are mainly used to fix the relative position between two parts. Special purpose screws such as eye bolts are used for lifting parts.
