Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 PSI ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in demanding industrial environments.
- Precise hex socket drive (2.5mm) allows for secure tool engagement and high torque application, minimizing stripping and improving assembly efficiency.
- Class 12.9 strength rating provides high fatigue resistance and load-bearing capacity for critical mechanical assemblies.
- Partially threaded design with 18mm thread length offers optimal grip and clamping force where full threading isn't required.
- Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability in global engineering projects.
- RoHS 3 and REACH compliance ensures environmental safety and regulatory acceptance for international supply chains.
Professional Applications & Engineering Value
Engineered for precision assemblies requiring high-strength fastening solutions, these M3 socket head cap screws address critical challenges in machinery, automation, and heavy equipment. The black-oxide alloy steel construction combats corrosion while maintaining Rockwell C37 hardness, ideal for environments exposed to vibration and dynamic loads. With a coarse 0.5mm pitch metric thread and Class 5g6g thread fit, they provide rapid installation and secure holding power in metals and engineered plastics. The partially threaded shank concentrates stress appropriately, preventing joint loosening in industrial applications where reliability is non-negotiable.
Specification Summary & Compliance
This screw features M3 x 0.5mm coarse threads with Class 5g6g tolerance per ISO metric standards, ensuring precise fit. Manufacturing adheres to DIN 912/ISO 4762 specifications for socket head cap screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety requirements for industrial use worldwide.
