Automobile screws have a very large impact on the car itself, whether it is for the maintenance of the car or for the safety of the car, this kind of screw has a very huge impact. Therefore, for automobile manufacturers, to manufacture high-quality automobiles, they must use high-quality automobile screws. For screw manufacturers, what they consider is how to make their own screws of better quality. To produce higher-quality screws, screw manufacturers only need to adopt various measures to ensure the quality of the screws. One of the methods is to carry out effective inspections to achieve the purpose of ensuring the high quality of screws. So how to grasp this kind of screw inspection?

The inspection of automobile screws is mainly divided into two aspects. The first aspect is after the screw production is completed, the inspection before electroplating is not carried out. The other is after the screw production is completed, the post-plating inspection is completed. First of all, let's take a look at the inspection before plating is not completed. This type of inspection mainly inspects the screws in two aspects. On the one hand, it is necessary to inspect the size of the screw to ensure that the size meets the relevant national regulations to ensure that the screw can be used normally. The other aspect is to check the tolerances. Make judgments to measure the overall quality of the screws produced. This is an important measure to ensure that the produced screws meet national regulations and customer requirements.

After talking about the inspection before electroplating, let's look at the automobile screw inspection after electroplating. In this part of the inspection, the two parts of the screw are mainly inspected, and the other part is to inspect the appearance of the screw potential to see how the screw after electroplating is effective. Another aspect is to see if the screws are damaged after plating. This part of the inspection is mainly to ensure that after the customer looks at the screw, there will be no obvious defects. In this part of the checklist, the following methods can often be used. The first method is to use an intuitive observation method, and you can also use some tools for measurement. These tools include the use of microscopes, micrometers, etc. to measure thickness.
