Normally, stainless steel screws are not easy to break when in use. Only in special circumstances can stainless steel screws break. So why do stainless steel screws break? What is the real reason for the fracture of stainless steel screws?
Based on the summary, Xiaorui told everyone that there are four common fracture situations of stainless steel screws.
1. The quality of the raw materials used for stainless steel screws is problematic, and the quality of the stainless steel screw wires is poor. There are many impurities and impurities, which result in insufficient hardness of stainless steel screws
2. The customer exerted excessive force when using stainless steel screws. Usually, you can do a torque test to see what the minimum breaking force is, and then adjust the torque. If high torque is required for the screw, heat treatment must be performed on the screw. Currently, stainless steel 410 material can be heat treated. The surface hardness of the heat-treated stainless steel 410 screw is HV580-680, and the core hardness is HV350-450.
3. Process issues in the production of stainless steel screws. For example, stainless steel screws with eccentric heads, as well as Q-values that are too deep and R-position designs that are too small during downward punching operations during production and manufacturing.
4. Check if the pre hole is suitable, as even if the pre hole is too small, the screw may break when inserted.
So when we buy stainless steel screws, we must recognize and take good care of them to prevent us from buying inferior products that may cause unnecessary trouble during use.
