Why can’t the long m3 screws be used?

Previously, Mr. Qi customized a long m3 screws here at Shi Shi Tong screw manufacturer. After receiving the screw, Mr. Qi carried out the assembly test and found that it could not be used. Why?

Later, after Mr. Yu tested it, it was discovered that the long m3 screws could not withstand enough force, so it could not be used. Then, Mr. Qi came to ask Shi Shi Tong screw manufacturers on how to solve this problem. Shi Shi Tong screw manufacturer asked Mr. Qi what the force of the screw is to bear. After knowing how much force the screw has to bear, we told Mr. Qi to change the diameter of the long M3 screw to 2.7mm-3.0mm because the diameter of the original rod is 2.1mm-2.4mm, and the force they can withstand is not large. So many poles.

According to our suggestion, Mr. Yan asked us to give him some long m3 screws samples for him to test, he will give us the cost of the sample. After receiving the modified sample of the screw, Mr. Qi took it and tested it and found that it was indeed usable.

Therefore, when ordering screws from the screw manufacturer, the buyer must not only provide the screw manufacturer with the size of the screw, but also the screw manufacturer to explain the use of the screw, the performance of the screw, etc., so that the screw manufacturer can provide you with the right size according to your requirements.
