Mr. Ma asked the Shi Shi Tong binding head sheet metal screws here at the Shi Shi Tong screw manufacturer a month ago.

Mr. Ma asked if we could make the M4*80 binding head sheet metal screws, the size of the head is in accordance with the standard. There is a 5mm long step under the head, and the thread length is 30mm, hexagonal socket groove type, stainless steel 304 material. Ask if we can produce this kind of screw. If it can be produced, let us provide the price to him.

After the price of the binding head sheet metal screws was reported to Mr. Ma. After a week, Mr. Ma said that he needed to make some changes to the design of his binding head sheet metal screws. The groove is preceded by a hexagon socket and needs to be changed to the inner plum. And Mr. Ma said that he would add a pattern on the head of the screw and ask if we can.

Mr. Ma sent us the pattern he wanted to design. Shi Shi Tong carefully evaluated it and determined that this pattern can be done. Just tell Mr. Ma that we can do it. After confirming that Shi Shi Tong can produce his binding head sheet metal screws, Mr. Ma told Shi Shi Tong that he would tell us and confirm the order after talking about the project.
