What causes the quality problems of self-tapping screws?

In our production process, there will definitely be some factors that cause the quality of our products to be unsatisfactory, sometimes because of our operational problems, sometimes because of equipment problems, etc. These factors will directly affect The quality of the product is the same for self-tapping screws. There are many reasons that affect quality problems. Let ’s take a look at it together.
Screw factory
1. When producing stainless steel self-tapping screw fasteners, the wire is defective. As a result, head screws will be produced. If the trace on the head of the screw is very shallow, we can still use it. But when the marks are deep and numerous, it will not only affect the appearance, but also be unusable. Or the diameter of the wire used is too large or too small, and the diameter of the thread produced in most cases will also be too large or too small, which makes it impossible to assemble.
2. When the machine is not adjusted properly, or if the mold used has a problem, the screws produced will also have problems.
3. There are problems with the design of stainless steel self-tapping screw fasteners. Sometimes the head is too large, the groove of the screw is deep, and the customer is unwilling to add an R angle under the head of the screw. This kind of screw is difficult to make during production, and the screw will break if accidentally Even if it is produced, it will be easy for customers to break when using it.
