Professional Applications & Engineering Value

This M6 flat head screw is engineered to address critical challenges in industrial settings where corrosion resistance and mechanical integrity are paramount. Crafted from 316 stainless steel and featuring a passivated finish, it excels in aggressive environments like chemical processing, marine hardware, and outdoor structures, preventing rust and degradation. The fully threaded design with a coarse thread pitch provides excellent grip and vibration resistance, reducing the risk of loosening under dynamic loads. The hex drive and flat head profile allow for quick, tool-friendly installation and a smooth, flush surface finish, ideal for applications where protrusion is not acceptable. By meeting DIN 7991 specifications, it ensures reliable performance in machinery, equipment assembly, and structural frameworks, delivering long-term engineering value with minimal maintenance.

Specification Summary & Compliance

This screw adheres to precise dimensional standards, including a thread fit of Class 6g per metric ISO tolerances, ensuring compatibility with standard nuts and threaded holes. It is manufactured in compliance with DIN 7991 for flat head screws, guaranteeing consistent quality in head diameter, thread size (M6 x 1mm), and length (16mm). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for various industrial and commercial uses.
