Screws can be divided into three categories according to their purpose: machine screws, set screws and special purpose screws.
The machine screw is mainly used for a tightly threaded part and a tight connection between a part with a through hole and does not require a nut fit (this type of connection is called a screw connection and is also a detachable connection; Fitted with a nut for a tight connection between two parts with through holes.) This is the most common screw.
The set screw is mainly used to fix the relative position between the two parts. Our common saying is "the head screw", which acts as the locating pin.
Special purpose screws such as eyebolts are used for lifting parts.
The grades of carbon steel bolts are divided into more than 10 grades of 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. The numbers before and after the decimal point respectively indicate the nominal tensile strength and yield ratio of the bolt material, for example: Marking 8.8 bolts indicates that the tensile strength of the material reaches 800 MPa, and the yield ratio is 0.8, that is, the yield strength reaches 800X0.8=640MPa.
