With the rapid development of the industry, the application of stainless steel self-tapping screw fasteners has become very extensive.
Then, when customizing stainless steel self-tapping screw fasteners, occasionally bad quality stainless steel self-tapping screws are ordered.
However, there are generally several cases of quality problems with stainless steel self-tapping screw fasteners:
One is that there is a problem with the wire when producing stainless steel self-tapping screw fasteners.
The resulting screws will have headshot problems. If the mark on the head of the screw is very shallow, we can still use it.


But when the marks are deep and too many, it will not only affect the appearance, but also make it unusable.
Or the diameter of the wire used is too large or too small. In most cases, the diameter of the thread produced will be too large or too small, resulting in assembly failure.
The second is that if the machine is not adjusted well during the adjustment, or the mold used is defective, the screws produced will also have problems.
Three are problems with the design of stainless steel self-tapping screw fasteners.
Sometimes the head is too big, the screw groove is deep, and the customer is unwilling to add an R angle under the screw head.
This kind of screw is difficult to make during production, and the screw will break if you are not careful. , Even if it is produced, the customer will easily break when using it.
