What causes the quality problems of fastener screws?

2023/07/22

With the rapid development of industrial production, the application of composite fasteners has become very extensive. In this way, when ordering combination screws, sometimes poor-quality combination fastener screws are purchased, and there are generally three situations in which quality problems occur with combination screws. One is that there is a problem with the cable when the combination screw is produced. As a result, the produced screws will have a head burst problem. If the impression on the head of the screw is relatively deep, we can still use it. But when the marks are deep and many, not only will it affect the appearance, but it will also make it unusable. Or the diameter of the cable used is too large or too small, and in most cases the diameter of the thread produced may also be too large or too small, resulting in failure to install. The second is that if the adjustment is not done properly during debugging and replacement, or the grinding machine used has problems, the produced screws will still have problems. The third is that there is a problem with the screw design of the combined fastener. Sometimes the top of the head is too big, the groove of the screw is very deep, and the customer is not willing to add an R angle under the head of the screw. This kind of screw cannot be done during production, and the screw will break if you are not careful. Even if it is produced, it will be easier for customers to break when using it. If there is a quality problem with the combination screw, there are many reasons, Maijin just mentioned a few types here.
