Stainless steel screws generally refer to steel screws that have the ability to resist corrosion from air, water, acids, alkalis, salts, or other media. They are usually not prone to rust, durable, and can be used in fields such as environmental protection equipment and communication devices.

Principles for selecting material for stainless steel screws:

The selection of stainless steel materials primarily considers the following five aspects.

1. Requirements for the mechanical properties of stainless steel screw material, particularly the tensile strength of stainless steel external hex bolts.

2. Requirements for material corrosion resistance due to working conditions.

3. Temperature requirements for the material's heat resistance performance (high temperature strength, oxidation resistance).

4. Requirements for material processing performance in terms of production process.

5. Additionally, factors such as weight, pricing, and procurement should all be considered.
