S-90854A341 M27 x 100 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength (150,000 psi) for reliable performance in high-stress industrial applications
• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in harsh environments
• High-strength Class 10.9 rating ensures consistent load-bearing capacity and structural integrity
• Precision metric threading (M27 x 3mm coarse pitch) provides secure fastening with reduced cross-threading risk
• Partially threaded design with 60mm minimum thread length optimizes clamping force distribution
• Rockwell C32 hardness maintains dimensional stability under heavy mechanical loads
• External hex drive with 41mm head width enables high-torque installation using standard tools

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this Class 10.9 hex head screw delivers critical performance where structural integrity matters most. The M27 metric coarse thread configuration ensures rapid assembly while maintaining vibration resistance in heavy machinery, construction equipment, and structural steel connections. The zinc yellow-chromate plating provides essential corrosion protection for outdoor installations and manufacturing environments exposed to moisture and chemicals. With its partially threaded design, the fastener concentrates clamping force precisely where needed, preventing joint relaxation under dynamic loads. The combination of 150,000 psi tensile strength and Rockwell C32 hardness makes it ideal for critical bolting applications requiring predictable failure margins and long-term reliability.

Specification Summary & Compliance

This metric hex head screw maintains Class 6h thread fit tolerance for precise engagement and meets ISO 4014/DIN 931 specifications for dimensional accuracy and mechanical properties. The 100mm length with 60mm minimum thread length ensures proper installation across various material thicknesses. Manufacturing complies with international standards for heavy-duty fasteners, providing consistent performance in regulated industrial applications requiring traceability and quality assurance.
