Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with Class 10.9 tensile strength (120,000 psi) for reliable performance in high-stress applications
- Superior corrosion resistance from black-oxide coating on alloy steel, extending service life in harsh industrial environments
- Optimal thread engagement with coarse 1.75mm pitch and Class 6g fit ensuring secure, vibration-resistant connections
- Efficient installation and removal through 8mm hex drive design, reducing assembly time and tool wear
- Flush mounting capability with standard 90° countersink angle and flat head profile for clean, aerodynamic surfaces
- Full-length threading providing maximum grip along the entire 20mm length for enhanced joint integrity
- Global compliance assurance meeting DIN 7991/ISO 10642 standards with RoHS 3 and REACH environmental regulations
Professional Applications & Engineering Value
Engineered for demanding industrial fastening scenarios, these M12 flat head screws solve critical challenges in heavy machinery, structural assemblies, and equipment manufacturing. The black-oxide alloy steel construction combats corrosion while maintaining Rockwell C32 hardness, preventing thread deformation under repeated stress. The coarse metric thread (1.75mm pitch) resists loosening in high-vibration environments, and the fully threaded design ensures uniform load distribution. With hex drive compatibility and standard countersink profile, they enable rapid installation in confined spaces while maintaining flush surfaces - ideal for automotive frames, construction equipment, and industrial conveyors where reliability and precision are paramount.
Specification Summary & Compliance
Manufactured to DIN 7991 / ISO 10642 specifications with Class 6g thread tolerance for precision fit. The metric coarse threading (M12 x 1.75mm) and 20mm length provide standardized dimensional accuracy. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across regulated industries. Class 10.9 strength rating guarantees consistent performance meeting international engineering standards for heavy-duty applications.
