Screw Manufacturing Processes and Material Selection

1. Manufacturing Methods

Cold heading: Suitable for mass production with low cost (e.g., standard parts below M6)

Turning: High precision, used for special threads (e.g., trapezoidal lead screws)

2. Material Selection

Carbon steel (Grade 8.8): General-purpose, requires zinc plating for rust prevention

Stainless Steel (A2-70): Corrosion-resistant, suitable for humid environments (e.g., port machinery)

Alloy Steel (42CrMo): High strength, used for critical load-bearing components (e.g., excavator booms)
