S-97478A113 M12 x 100 mm DIN 6914, ISO 7412 Metric High-Strength Steel Heavy Hex Head Screws for Structural Applications

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 PSI ensures reliable performance in demanding applications, reducing the risk of fastener failure.
• Superior corrosion resistance from hot-dipped galvanized steel coating extends service life in harsh industrial or outdoor environments.
• High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining structural integrity under repeated stress.
• Coarse thread design with Class 6g fit allows for faster assembly and secure fastening in various materials.
• Partially threaded shank offers optimal grip length (77mm) for precise clamping force distribution in structural connections.
• External hex drive compatibility enables easy installation with standard tools, improving workflow efficiency.
• Compliance with DIN 6914/ISO 7412 standards guarantees dimensional accuracy and interchangeability for global engineering projects.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M12 hex head screws deliver critical reliability in construction, machinery assembly, and infrastructure projects. The hot-dipped galvanized steel construction provides a robust barrier against corrosion, significantly extending service life in exposed or high-moisture environments. With a Class 10.9 strength rating and 150,000 PSI tensile strength, these fasteners withstand extreme vibrational loads and dynamic stresses without compromising joint integrity. The coarse metric thread (1.75mm pitch) ensures rapid installation in steel frameworks and concrete anchors, while the partial threading design prevents thread damage during insertion and allows for precise clamp load distribution. Ideal for structural steel connections, heavy equipment manufacturing, and renewable energy installations where DIN 6914 compliance is required for standardized European engineering specifications.

Specification Summary & Compliance

This M12 x 1.75mm hex head screw features precise Class 6g thread tolerance for consistent fitment and meets DIN 6914 / ISO 7412 manufacturing specifications. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries. With dimensions including 100mm total length, 77mm grip length, and 21mm hex head width, it maintains strict metric standardization for global engineering applications.
