Why does stainless steel screw break?

1. The quality of raw materials used for stainless steel screws is not good, and the quality of stainless steel screw wire is not good. There are many impurities, impure, resulting in stainless steel screw hardness is not enough
2. When customers use stainless steel screws, they use too much force. General test torque to see how much the minimum breaking force is, and then adjust the torque.
3. The production process of stainless steel screws. For example, the stainless steel screw with eccentric head and eccentric, the Q value is too deep and the R position design is too small during the production and manufacturing.
Of course, stainless steel screw fracture certainly more than the above three reasons. But the above three reasons are the main causes of stainless steel screw fracture. When stainless steel screw fracture is found, it can be checked step by step. Let’s see what causes it.
