Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide steel coating, extending service life in demanding industrial environments
- Superior holding power from 130,000 psi tensile strength and Rockwell C27 hardness, preventing fastener failure under high stress
- Secure anti-rotation locking through integrated serrations, eliminating loosening from vibration in machinery and equipment
- Quick installation and removal with external hex drive and 13mm head width, compatible with standard tools for maintenance efficiency
- Distributed load bearing via 18.2mm flange diameter, reducing surface pressure and material damage in assembly applications
- Reliable thread engagement with Class 6g metric coarse threads, ensuring consistent fastening in high-volume production lines
- Full-length threading providing maximum grip along the entire 16mm shaft, ideal for through-hole applications
Professional Applications & Engineering Value
Engineered for industrial machinery, automotive assemblies, and heavy equipment, these M8 hex head screws address critical vibration resistance and corrosion protection needs. The black-oxide steel construction withstands harsh operating conditions while the serrations locking feature prevents costly downtime from loosened fasteners. With coarse metric threading and Class 6g thread fit, these fully threaded screws maintain precise tolerances in high-volume manufacturing environments. The integrated flange design distributes clamping force effectively, protecting sensitive components from surface damage during repeated maintenance cycles.
Specification Summary & Compliance
Manufactured to metric ISO standards with Class 6g thread fit tolerance and M8 x 1.25mm coarse pitch threading. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for global industrial applications. Features fully threaded design with 16mm length and 18.2mm flange diameter for consistent performance across production batches.
