• Precise thread engagement with Class 6g thread fit and coarse 2mm pitch ensuring secure, vibration-resistant fastening
• Efficient installation through the 10mm hex drive and standard flat head profile, allowing quick assembly with standard tools
• Full-threaded design providing maximum grip length and uniform load distribution across the entire 45mm length
• Global compliance assurance meeting DIN 7991/ISO 10642 standards plus RoHS 3 and REACH regulations for international project suitability
• Optimized countersink performance with 90° angle enabling flush mounting in prepared surfaces for clean, professional finishes

Professional Applications & Engineering Value

These M16 flat head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The black-oxide alloy steel construction combined with Class 10.9 strength rating addresses common failure points in heavy machinery, structural steel connections, and industrial equipment subjected to dynamic loads and environmental exposure. The fully threaded metric screw design with coarse 2mm pitch ensures rapid installation and superior holding power in steel-to-steel applications, while the hex drive configuration permits high-torque installation without cam-out. Engineered to DIN 7991/ISO 10642 standards, these countersunk screws provide reliable performance in automotive, construction, and manufacturing applications where vibration resistance and long-term reliability are essential.
