S-97478A132 M16 x 160 mm DIN 6914, ISO 7412 Metric High-Strength Steel Heavy Hex Head Screws for Structural Applications

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with Class 10.9 high tensile strength (150,000 psi) for reliable performance in demanding structural and machinery applications.
• Superior corrosion resistance due to hot-dipped galvanized steel construction, extending service life in harsh outdoor or industrial environments.
• Optimized for high-strength bolting in steel structures, complying with DIN 6914/ISO 7412 standards for consistent quality and interchangeability.
• Enhanced grip and stability with a coarse M16x2 mm thread and Class 6g fit, ensuring secure fastening even under vibration and dynamic loads.
• Efficient installation and removal using standard external hex drive tools, reducing assembly time and labor costs.
• Durable surface hardness (Rockwell C32) minimizes wear during installation and resists damage in heavy-duty use.
• Partial threading design provides an unthreaded shank for precise clamping in connected materials, improving joint integrity.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial and construction applications, this M16 hex head screw delivers critical reliability where failure is not an option. The hot-dipped galvanized steel offers a robust barrier against rust and chemical exposure, making it ideal for outdoor structures, bridges, and machinery exposed to weather or corrosive agents. Its Class 10.9 high tensile strength and coarse metric thread ensure that the fastener maintains clamp load under extreme tension and vibration, preventing loosening in dynamic environments. By meeting DIN 6914/ISO 7412 specifications, it guarantees dimensional accuracy and compatibility with standardized components, streamlining procurement and assembly processes for engineers and contractors focused on safety and longevity.

Specification Summary & Compliance

This M16 x 2 mm hex head screw features a metric coarse thread with Class 6g tolerance for precise fit, a partially threaded design with 28 mm thread length and 132 mm grip length, and overall length of 160 mm. It is manufactured in accordance with DIN 6914 (equivalent to ISO 7412) for high-strength structural bolting. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to environmental and safety regulations for hazardous substances.
