In the process of our production, there will definitely be some factors that lead to the quality of our products, sometimes because of our operational problems, and sometimes because of equipment problems, etc., these factors will directly affect The quality of the product, the self-tapping screws are the same, there are many reasons that affect the quality problem, let's take a look at it together.
1. When producing stainless steel self-tapping screws, there is a problem with the wire. The resulting screw will have a headshot problem. If the trace on the head of the screw is very shallow, we can still use it. But when the traces are deep and there are many, it will not only affect the appearance, but also will not be usable. 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 failure to assemble.
2. There is no debugging when the machine is adjusted, or there is a problem with the mold used, and the screw produced will also have problems.
3. There are problems with the design of stainless steel self-tapping screws. Sometimes the head is too large, the slot of the screw is very deep, and the customer is not willing to add the R angle under the head of the screw. This kind of screw is very difficult to manufacture in the production, and the screw will be broken if not careful. Even if it is produced, the customer will be easily broken when using it.
