- High hardness rating of Rockwell C37 provides excellent wear resistance and durability for repeated use.
- Precise Class 5g6g thread fit guarantees smooth assembly and secure fastening, minimizing production delays.
- Standard hex drive design with 2.5 mm drive size allows for easy installation and removal using common tools.
- Partially threaded shank offers optimal grip and clamping force where needed, enhancing joint integrity.
- Compliance with DIN 912 ensures consistent quality and interchangeability in metric fastener systems.
Professional Applications & Engineering Value
This M3 socket head cap screw is engineered to address critical challenges in industrial assembly, such as vibration resistance and long-term reliability. The black-oxide alloy steel construction combats corrosion, making it ideal for machinery, automotive, and electronics where exposure to moisture or chemicals is common. With a coarse thread pitch of 0.5mm and right-hand thread direction, it facilitates quick installation and high clamping force, reducing assembly time while maintaining Class 12.9 strength. The partially threaded design concentrates stress effectively, preventing loosening in dynamic applications and ensuring stable connections in precision equipment.
Specification Summary & Compliance
This screw adheres to DIN 912 standards with a Class 5g6g thread fit for metric precision. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory approval for global industrial use. Dimensions include an M3 thread size, 0.5 mm pitch, and 60 mm length with a minimum thread length of 18 mm, providing consistent performance in demanding applications.
