How to choose the screw material to meet the strength grade you need?

Core Selection Logic

Based on screw specifications (diameter M1~M6 for small sizes, M6~M12 for medium sizes, and above M12 for large/extra-large sizes), combined with the three key factors of strength requirements, processing technology, and service environment, the following material solutions are recommended:

Material Selection Table

Size Category	Recommended Material	Strength Grade	Core Advantages	Typical Application Scenarios
Small sizes (M1–M6)	10B21	10.9/12.9 grade	High cold-heading efficiency, low cost	Electronic devices, small mechanical fasteners
Medium sizes (M6–M12)	40Cr / ML40Cr	10.9/12.9 grade	Balanced mechanical properties, mature process	Automotive parts, main connections in industrial equipment
Large/Extra-large sizes (M12+)	SCM435 (35CrMo) / SCM440 (42CrMo)	10.9/12.9 grade	Ultra-high stre
