thread forming screw customized, shi shi tong

In December, We received an inquiry from a customer. There was a picture of the screw he was using before, indicating that he would like to purchase this thread forming screw again. In the customer’s drawing, the specification, material, and surface treatment of the screw are marked, but it does not show that the screw is thread forming screw. Due to the problem of light, the triangular thread is not clearly seen in the real drawing. And the customer’s real picture of the screw is mechanical teeth. We all know, the screw of the general triangle thread is from the tapping thread, the screw of the triangle thread of a few machine threads.

After that, please confirm to the customer whether this screw is for machine thread forming screw. The customer is sure to say triangle thread. Then I quoted the price to the customer. The customer said the price was ok and confirmed the order soon. During the production process and shipment of the thread forming screw, we sent the production picture of the screw and the measurement result of the screw to the customer, indicating that the triangle screw is not out of tolerance so that the customer can rest assured.
