Which hardware factory makes self-tapping screws well? Affordable?

Shantou, Shenzhen, Hangzhou and other places can do well. Recently, I saw a company called "Shantou Hegu Hardware Factory". You can search and ask.

There are many manufacturers of self-tapping screws. At present, in Shenzhen, Hangzhou, Shantou and other places, the screws made are very good. In terms of price, it depends where you are. Considering the mode of transportation and your location, the price is different, not to mention the same service. I used to work in Shenzhen, but the company has another office in Shantou. I also want some self-tapping screws, so I choose them according to various conditions. Finally, I decided to go to a hardware factory in Shantou, called Shantou Hegu Hardware Factory. At that time, that factory helped me design the screw pattern, and I arranged for Shantou staff to go to that hardware factory to see the samples. If you are far away, you can also ask the factory to mail the samples to you. You can also visit this house.
