Why Do 3mm Pan Head Screw Stick Together?

Mr. Zhang purchased a batch of 3mm pan head screw from Shi Shi Tong screw manufacturers half a month ago and asked us to produce the screws after electroplating.

Mr. Zhang said that the 3mm pan head screw that his previous suppliers gave him would always be like this. The number is not good, but the NPL ratio is basically above 5%. This has been reported to the supplier several times. Still no improvement. Then Mr. Zhang said that I hope that we will not see this happen.

This is the case with Mr. Zhang’s 3mm pan head screw, mainly because the threaded parts collide with each other during plating to stick together during plating. Generally, such screws need to be added with relatively large screws during electroplating to reduce the occurrence of such a situation.

Therefore, before the shipment, Shi Shi Tong not only repeatedly explained with the electroplating factory to reduce the occurrence of this situation but also checked the shipment. Mr. Zhang also checked once after receiving the goods, saying that the quality of the 3mm pan head screw we gave him was very satisfactory.
