S-97478A178 M27 x 75 mm DIN 6914, ISO 7412 Metric High-Strength Steel Heavy Hex Head Screws for Structural Applications

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from hot-dipped galvanized steel coating, ensuring long-term reliability in harsh industrial environments
• Superior load-bearing capability with 150,000 psi tensile strength and Class 10.9 grade, providing reliable performance in heavy-duty applications
• Optimized thread engagement with Class 6g thread fit and M27x3 coarse thread pattern, enabling faster assembly and reduced cross-threading risks
• Enhanced driving efficiency through external hex drive and 48mm head width, allowing high-torque installation with standard tools
• Controlled clamping force with 38mm grip length and partial threading, preventing joint loosening under dynamic loads
• Consistent mechanical properties with Rockwell C32 hardness, maintaining structural integrity through repeated stress cycles
• Global compliance assurance meeting DIN 6914/ISO 7412 specifications, ensuring interchangeability and quality across international projects

Professional Applications & Engineering Value

These M27 hex head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The hot-dipped galvanized steel construction provides superior protection against environmental degradation, making them ideal for structural steel connections, heavy machinery assembly, and infrastructure projects exposed to weather elements. The metric coarse thread (M27x3) with Class 6g tolerance ensures reliable engagement in thick materials while the partial threading design concentrates stress away from the head, preventing thread stripping in dynamic load conditions. With 150,000 psi tensile strength and Rockwell C32 hardness, these Class 10.9 fasteners maintain clamping force in vibration-prone applications, from industrial equipment to construction frameworks requiring DIN 6914/ISO 7412 compliance.
