Why do the flat head undercut machine screws need to open the mold?
Mr. Xie found the Shi Shi Tong screw manufacturer a few days ago and said he wanted to customize a flat head undercut machine screws . He said that he saw on the Internet that we could do his type of screw, gave the drawings to us, and asked if we could do this for him? After carefully reviewing the drawings of Mr. Xie, we told Mr. Xie that this flat head undercut machine screws is to be opened. Mr. Xie said why, his screw is the same diameter as the thread we showed on the Internet, and the size of the head is the same? Although the thread diameter of the flat head undercut machine screws of Mr. Xie and the size of the head are the same as those shown on the Internet. However, the thread length of the countersunk head screw of Mr. Xie is different from the size of the step position. If the steps of the step screws are different, it is generally necessary to open the mold and not share the mold. Therefore, it is necessary to open the mold.
