With the rapid development of the industry, the application of combined screws has also become very widespread. Then, when customizing the combined screws, occasionally order the quality combined screws, and there are several cases of quality problems in combination screws:

One is a problem with the production of combined screws. The screw that caused the production will appear. If we are very shallow in the head of the screw, we can use it. But when traces are very deep, more times, it will not only affect the appearance, but will not be used. Or use the wire diameter is too large or too small, and the threaded diameter produced in most cases will be too large or too small, resulting in unapplied.

The two are no debugging during the transfer, or there is a problem with the mold used, and there will be problems.

The three is a problem with the design of the combination screw. Sometimes the head is too large, the slot of the screw is very deep, the customer is not willing to add R corners below the head of the screw, this screw is difficult to do when production, one accidentally screws Even if it is produced, the customer will be easily broken when using it. If there is a quality problem of combined screws, there are many reasons, just simply talk about several.
