With the continuous development of technology and electronic products, many products will use precision screws, Regardless of their quality,tolerance, or strict material selection, there are some rules, the precision screw material selection is mainly from the following aspects to consider, will give you a brief introduction:  
1. The material of precision screw has the requirements in mechanical equipment performance level and compressive strength level  
2. Provisions on the corrosion resistance of materials  
3. The operating temperature of the material's high temperature performance (high temperature compressive strength, oxidation resistance) layer  
4. Regulations on production and processing performance of materials from the production process level
5. Other aspects, such as net weight, price, purchase and many other factors also need to be considered  
In our life, the common screws are all often refers to the precision screws are austenitic, people use the raw materials generally use austenitic stainless steel 304,316,316L and low nickel 201, etc.  As a manufacturer which has 20 years experience in precision screw customization, we can custom according to your material requirements, if necessary, you are welcome to inquire!
