Professional Applications & Engineering Value

This M8 flat head screw in 316 stainless steel is engineered to address critical challenges in industrial and marine settings where corrosion and mechanical stress are prevalent. The passivated finish enhances the innate corrosion resistance of the material, making it suitable for applications exposed to moisture, chemicals, and salt spray. Its fully threaded design with a coarse thread pitch ensures maximum grip and load distribution in materials like metal, plastic, and wood, reducing the risk of loosening under dynamic loads. The hex drive and flat head profile allow for efficient installation in countersunk holes, providing a flush surface that minimizes protrusion and improves safety in machinery, structural assemblies, and equipment housings. By complying with DIN 7991, it delivers reliable performance in metric-based engineering projects, from automotive to construction.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a thread fit of Class 6g per metric specifications, ensuring compatibility and ease of assembly. The manufacturing follows DIN 7991 for flat head screws, covering head diameter tolerance (-0.43 to 0 mm) and thread parameters (M8x1.25 coarse, right-hand). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and supporting environmental safety in industrial applications.
