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 extends service life in harsh or humid industrial environments.
- Precise Class 5g6g thread fit guarantees smooth assembly and secure fastening, minimizing play and vibration loosening.
- High hardness (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Compact 1.5mm hex drive design allows for easy installation in confined spaces with standard tools.
- Full threading along the 3mm length offers maximum grip and adjustability for precise component positioning.
- Compliance with DIN 912/ISO 4762 standards ensures interchangeability and consistent quality for global engineering projects.
Professional Applications & Engineering Value
This M2 socket head cap screw is engineered from black-oxide alloy steel to address critical challenges in precision assemblies, such as electronics, machinery, and automotive subsystems. The coarse thread (0.4mm pitch) and Class 12.9 strength rating provide robust clamping force and vibration resistance, preventing loosening under dynamic loads. The fully threaded design ensures uniform stress distribution, while the socket head with a 1.5mm hex drive facilitates secure tool engagement in tight spaces. Ideal for applications demanding high tensile strength and corrosion resistance, this fastener enhances reliability in automated equipment, sensor mounts, and compact mechanical designs.
Specification Summary & Compliance
This metric screw features M2 x 0.4mm coarse threads with a Class 5g6g thread fit per ISO standards, ensuring dimensional accuracy. It is manufactured to meet DIN 912/ISO 4762 specifications for socket head cap screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally sensitive and regulated industries.
