- Industry-standard compatibility meeting ISO 4029 specifications for guaranteed interchangeability
- Environmentally compliant construction that satisfies RoHS 3 and REACH regulations for global applications
Professional Applications & Engineering Value
This M8 set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The alloy steel construction with Rockwell C45 hardness maintains structural integrity under extreme mechanical stress, while the serrations locking mechanism provides permanent anti-rotation security that conventional fasteners cannot match. The cup tip design concentrates pressure for superior grip on shafts, gears, and collars in power transmission systems, automotive assemblies, and heavy machinery. With coarse thread spacing and Class 6g thread fit, installation is optimized for production environments where speed and reliability are essential. This hex headless set screw solves common industrial challenges of component creep and positional drift in high-vibration applications.
Specification Summary & Compliance
This metric set screw features M8 x 1.25mm coarse thread spacing with Class 6g thread fit tolerance per ISO metric standards. The 12mm length and 4mm hex drive conform to ISO 4029 dimensional specifications for set screws. Manufacturing complies with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) chemical regulations, ensuring environmental compliance for international industrial applications.
