Screws, nuts, nuts, bolts... For those who are new to machinery and processing, none of them can be "distinguished". Today, I will take you to talk carefully about what these are.
1: In fact, according to the standard, there is no "screw" and "nut". Unexpectedly, "screw" is a common name, and anything with external threads can be called "screw" "nut" is a common name, and the standard should be called "nut". The shape of the "nut" is usually hexagonal, and the inner hole is an internal thread, which is used to cooperate with the [bolt] to tighten the related parts. The head of the "bolt" is generally hexagonal, and the rod has an external thread.
2: Thread is a shape with uniform spiral lines and protrusions on the outer or inner surface of a solid. Generally, it has the following functions: Fastening and connection function: Applicable to most screw products at this stage.
When choosing the appropriate bolt and nut standard, you need to consider the following aspects
1: Compatibility: When purchasing bolts and nuts, you need to consider whether they can match each other, that is, whether they can be combined together. Generally, it is necessary to consider the nominal diameter, options, pitch and number of threads, and tooth type.
2: Color and length: According to the place and scene of use, choose a nut color similar to the color of the connected object. At the same time, make sure that the length of the nut is not too long or too short, so as not to affect the bite stability, appearance or interfere with the use of other parts.
3: Head type: When choosing the head type of the nut, it is usually necessary to consider its anti-disassembly performance, and it may adopt a hexagonal or other special shapes. In some cases, the appearance of the nut is also considered. If the nut needs to be stable and reliable, you may choose a drop-resistant nut or a nut with a gasket.
Therefore, when selecting nuts, be sure to choose the appropriate nut product according to the usage scenario.
