  Button head self tapping screws process The production of  button head self tapping screws  has always required a standard process. Don’t look at the size of the screws, but the screwing process must not be underestimated. The screws are small, and the process can be produced quite a lot! Through the screw, the factory sees the screwing process. How is the screw made? In fact, from the process, I believe you will have a clearer understanding. The  button head self tapping screws  production process mainly includes seven steps of annealing, pickling, drawing, forming, caulking, heat treatment, and surface treatment. Annealing is mainly to heat the wire to a suitable temperature for a certain period of time, and then slowly cool to adjust the crystal, reduce the hardness, and improve the normal temperature processability of the wire. Pickling is designed to remove the oxide film on the surface of the wire and form a phosphate film on the metal surface to reduce ...

  Can the button head self tapping screws be so short?   When many customers order button screws from Shi Shi Tong, they are basically threaded, and there are few self-tapping threads. The button screw that Mr. Chu needs is not the thread of the machine, but the  button head  self tapping screws . There are two types of  button head self tapping screws  requested by Mr. Chu. One is ST2.9*12 and the other is ST2.9*2.5. The pitch requirement is 1.1, which is self-tapping. And Mr. Chu said that if the short one cannot be produced, the length can be cut to the length he needs.   According to Mr. Chu’s request, we said that it can be produced, and it is recommended that Mr. Chu’s short  button head self tapping screws  should lengthen the length. Because this length is too short, we are worried that it will not be able to tighten. Mr. Chu said that he did not need to produce according to his requirements.

Screw fasteners are inseparable from our lives. As long as it is a mechanical device, there are basically screw fasteners on it, and it is difficult to find the screw fastener on it. When we use screw fasteners, they are generally used together with matching nuts, gaskets, and the like. But when we used stainless steel screws, we found that the  stainless button head cap screws  were locked up after a while. Why is this? There are several reasons that may cause this to happen: one is the 304HC material used for stainless button head cap screws, and the nut material used is also 304HC, which will lock up. The second is that during the tightening process, the force is uneven or inclined. The third is that when the tightening is too strong or the speed is too fast, the friction caused by the stainless steel screws becomes soft and the adhesion occurs. Fourth, when assembling, the screws that are screwed in are not perpendicular to the threaded holes. Shi shi tong scre...
