Recently, I heard from customers that there have been some scratches on the bolts and screws they purchased from other manufacturers. At first, they thought it was the damage of freight logistics. Later, they found that there were scratches every time. Because the fake and inferior bolts had already seriously harmed the quality of their products, they found that the bolts were more beautiful than before We are generous and good-looking. We have reached the project cooperation, but we still hope that you can answer their questions. Next, we will explain why our bolts are different from others, not only without scratches, but also more beautiful

1. If there are scratches on the screw, first check whether it is not placed properly under the condition of entering the mold. Since all iron core pulling rivets are made in the grinding tool of cold heading machine, the grinding tool immediately determines the appearance and quality of the screw.

2. If there is no problem with the abrasives, it is likely that the thread has not been cut completely. At this time, it is necessary to check whether the scissors used for thread breaking is abnormal. If there is any abnormality, it needs to be removed immediately.

3. This point is very easy to be ignored by many people. Because the two points in front of us can be checked out by ordinary teachers, we must have working experience in stainless steel sea horse core pulling rivet. If we don't find any problems after checking the abrasives and wounds, it is very likely that the equipment has not been cleaned up and tidy. If there is sediment on the equipment, then the bolts will inevitably have scratches. Therefore, we should pay attention to this
