Jul 13, 2019

Screw, also known as "screw"

(screw), "screw" (screw). In fact, screw is a generic term, and screw, screw are different from each other. The screw is generally called wood screw; it is the kind with a sharp head at the front, with a large pitch, and is generally used to fasten wood and plastic parts. Screw is machine screw (mechanical screw), is the kind of front flat head, pitch is small, uniform, generally used to fasten metal, machine parts. The stud has no head, only a kind of fastener with threads at both ends. When connecting, one end must be screwed into the parts with internal threaded holes, the other end must pass through the parts with through holes, and then the nut is screwed so that the two parts are tightly connected into a whole.

This form of connection is called stud connection and also belongs to removable connection. It is mainly used in situations where one of the connected parts is thicker, requires compact structure, or is not suitable for bolted connection because of frequent disassembly.

Screw: A cylinder with spiral grooves on its outer surface or a cone with conical spiral grooves. Screws have different heads, such as the head in the picture called the outer hexagonal screw.

There are others, such as large flat screw, hexagonal screw and so on.

Bolts: Mechanical parts, cylindrical fasteners with threads with nuts. A type of fastener consisting of a head and a screw (a cylinder with external threads) is required to be fitted with a nut to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is screwed off from the bolt, the two parts can be separated, so the bolt connection belongs to the removable connection.
