1. Specifications: M4-M10 are metric screws, -1/4-20 and 5/16-18 are imperial screws,
2. Material selection: 304 stainless steel has good corrosion resistance and is suitable for humid or corrosive environments. Carbon steel zinc plating has high strength, but may rust under certain conditions and is commonly used for general mechanical and construction purposes.
3. Surface treatment: Zinc coating can provide additional anti-corrosion protection and extend the service life.
4. Application scenario : Used for components that require frequent adjustment or replacement, such as fixing parts of badminton rackets.
5. Performance and Strength : The load-bearing capacity of screws of different specifications varies, and the appropriate model should be selected according to the actual load requirements.
