S-95327A716 M12 x 120 mm ISO 4014, DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Load-Bearing Capacity: Class 10.9 strength grade and 150,000 psi tensile strength ensure reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Superior Corrosion Protection: Zinc yellow-chromate plating provides excellent resistance to rust and environmental degradation, extending service life in harsh industrial settings.
• Optimized Thread Design: M12 coarse thread with 1.75mm pitch offers faster installation and reduced cross-threading risks compared to fine-pitch alternatives.
• Secure Torque Application: External hex head design with 19mm width enables high-torque tightening using standard tools, ensuring vibration-resistant connections.
• Precision Manufacturing: Class 6h thread fit guarantees consistent engagement and proper clamping force distribution across connected components.
• Enhanced Durability: Rockwell C32 hardness provides optimal balance between strength and toughness, resisting wear during repeated assembly/disassembly cycles.
• Versatile Partial Threading: 30mm minimum threaded portion allows for both shear and tension applications while maintaining unthreaded shank strength.

Professional Applications & Engineering Value

These M12 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The Class 10.9 steel construction combined with Rockwell C32 hardness addresses common failure points in machinery assembly, construction equipment, and structural frameworks. The zinc yellow-chromate plating specifically counters corrosion challenges in manufacturing environments exposed to moisture, chemicals, or outdoor conditions. With partial threading design, these metric coarse thread fasteners provide optimal clamp load distribution while the external hex drive ensures reliable installation in confined spaces. Meeting ISO 4014/DIN 931 specifications, they offer interchangeable replacement parts for European and international equipment manufacturers.

Specification Summary & Compliance

Manufactured to ISO 4014/DIN 931 standards with Class 6h thread fit tolerance ensuring precision mating with corresponding nuts. The metric coarse thread (M12 x 1.75mm) follows ISO metric thread specifications while the partial threading maintains 30mm minimum thread length. Zinc yellow-chromate plating complies with RoHS and REACH environmental directives. Class 10.9 designation confirms compliance with ISO 898-1 mechanical properties standards for high-strength steel fasteners.
