Professional Applications & Engineering Value
Engineered for high-stress industrial applications, these M8 flat head screws deliver exceptional performance where reliability is critical. The black-oxide alloy steel construction provides superior corrosion resistance while maintaining Rockwell C32 hardness for long-term durability in harsh environments. The coarse 1.25mm pitch threading ensures rapid installation and superior vibration resistance, making them ideal for machinery, automotive assemblies, and structural frameworks. The fully threaded design combined with Class 10.9 strength rating guarantees maximum load distribution and prevents joint failure in high-torque applications. These metric screws are particularly valuable in applications requiring flush mounting with their 90° countersink angle and consistent performance across temperature variations.
Specification Summary & Compliance
These flat head screws feature precise Class 6g thread fit tolerance with M8 x 1.25mm coarse thread specifications. Manufactured to DIN 7991/ISO 10642 standards with 16mm length, 16mm head diameter, and 5mm hex drive configuration. The fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across global markets.
