Production of black countersunk self tapping screws or such manufacturers worry-free

Mr. Li is being an electronic product company. Last year, he found a screw manufacturer near his company to make black countersunk self tapping screws. There was no big problem when it was just starting to supply. However, after the screw has been used for a while, it will basically rust.

Mr. Li has responded to this issue several times with this manufacturer. They also assured Mr. Li that this problem will not occur again when the black countersunk self tapping screws are used for the next time. After the next delivery, there was no such problem, but a new problem appeared, that is, some of the screws were eccentric.

Mr. Li and the manufacturer indicated that they would like to have a full inspection of the manufacturer and provide a material report. Mr. Li thinks that he has said this to the manufacturer, and there will be no problem when the next supply. As a result, when he received the goods again, there was still a problem.

After that, Mr. Li found a new manufacturer and found Shi Shi Tong. Mr. Li told Shi Shi Tong that he hopes that there will be no problems when he supplies the goods, and he will provide him with the report he requested. According to Mr. Li’s request, we carried out a full inspection of the black countersunk self tapping screws at the time of shipment to ensure that there were no problematic screws. And provide the corresponding report to Mr. Li.

After giving Mr. Li several goods, Mr. Li said that it was too worry-free to cooperate with us, and there was no problem with the screws provided to him, which made him feel relieved.
