- Secure anti-loosening performance with serrated locking features under the flange for vibration-resistant assemblies
- High tensile strength of 130,000 psi ensures reliable load-bearing capacity in demanding applications
- Quick installation and removal with standard 13mm external hex drive and fully threaded design
- Superior thread engagement with Class 6g metric coarse threads for easier alignment and reduced cross-threading risks
- Distributed load bearing thanks to the 18.2mm flange diameter, minimizing surface damage
- Industry compliance assurance with RoHS 3 and REACH regulations for safe usage in regulated sectors
Professional Applications & Engineering Value
These M8 hex head screws with black-oxide steel construction address critical industrial challenges where corrosion resistance and vibration durability are paramount. The coarse thread (1.25mm pitch) and Class 6g thread fit enable rapid assembly in machinery, automotive, and structural frameworks, reducing installation time while maintaining precision. The combination of Rockwell C27 hardness and 130,000 psi tensile strength ensures longevity under dynamic loads, while the flanged design with serrations provides stable locking without separate washers. Ideal for industrial equipment, these screws deliver consistent performance in environments exposed to moisture, chemicals, or mechanical stress, supported by full threading for maximum grip across the 30mm length.
Specification Summary & Compliance
This metric hex head screw features M8 x 1.25mm coarse threads with Class 6g tolerance for reliable fit, fully threaded along the 30mm shank. Manufactured from hardened steel with a black-oxide finish, it meets Rockwell C27 hardness and 130,000 psi tensile strength standards. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety adherence for global industrial use.
