Fastener tips: common problems with screws

The first problem is that the screw head is deformed. This problem is likely to be caused by the improper adjustment of the screw mold or the improper adjustment of the screw mold during the production process.

Problem two, the head of the screw is not round. This problem also often occurs in the process of screw production by fastener companies. Generally, the screw die and punch die are not full during molding.

Question three, the screws have some burrs. This is mainly due to the fact that the mold is not well formed at the first punch, and this problem will be caused when the punch is relatively short. (Guide: Knowledge about the material of stainless steel fasteners)

Question four, cracks appeared on the head of the screw. This may be caused by the unqualified screw wire. Therefore, before we produce the screw, we must carry out strict inspection on the screw wire. When we find the unqualified wire, we must not produce it. For example, when we are testing, each data must be out, so that we can judge whether the wire is qualified or not. There are also problems that the mold is incorrectly placed and the lubricant is forgotten.
