- Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding environments.
- Precise and reliable fastening ensured by Class 5g6g thread fit and M3 x 0.5mm coarse thread for quick assembly and vibration resistance.
- Easy installation and removal with a standard 2.5mm hex drive socket head, allowing high torque application without stripping.
- Optimized for partial threading with 18mm min thread length on a 30mm screw, providing secure grip where needed while reducing weight.
- Compliance with international standards including DIN 912/ISO 4762, ensuring consistent quality and interchangeability.
- Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting global regulatory requirements.
Professional Applications & Engineering Value
This M3 socket head cap screw is engineered to address critical challenges in machinery, automotive, and precision equipment assembly. The black-oxide alloy steel construction offers enhanced resistance to rust and wear, while the Class 12.9 strength and Rockwell C37 hardness prevent failure under heavy loads and vibrations. The coarse thread (0.5mm pitch) and right-hand threading facilitate faster installation and provide reliable holding power in metals and composites. Ideal for applications requiring high tensile strength and durability, such as motor mounts, tooling jigs, and structural frames, this screw ensures long-term performance with minimal maintenance.
Specification Summary & Compliance
This product adheres to precise metric dimensions including M3 thread size, 0.5mm pitch, and 30mm length with a Class 5g6g thread fit for consistent accuracy. Manufactured to DIN 912 and ISO 4762 standards, it guarantees dimensional uniformity and reliability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), it meets environmental and safety regulations, making it suitable for global industrial supply chains.
