S-97478A196 M30 x 130 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 high-stress industrial environments, reducing the risk of fastener failure.
• Superior corrosion resistance from the hot-dipped galvanized steel coating extends service life in harsh or outdoor conditions, minimizing maintenance needs.
• High hardness rating (Rockwell C32) provides excellent wear resistance and durability, maintaining structural integrity under repeated loads.
• Precision Class 6g thread fit with coarse 3.5 mm pitch allows for faster assembly and secure fastening, even in vibrating applications.
• Partial threading design offers optimal grip length (88 mm) for controlled clamping force, preventing joint loosening in heavy machinery.
• Compliance with DIN 6914/ISO 7412 standards guarantees dimensional accuracy and interchangeability, streamlining procurement and installation processes.
• RoHS 3 and REACH compliance ensures environmental safety and regulatory adherence, supporting sustainable and responsible manufacturing practices.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M30 hex head screw combines hot-dipped galvanized steel with a Class 10.9 strength grade to address critical challenges in construction, machinery, and structural assemblies. The coarse metric thread (3.5 mm pitch) and external hex drive facilitate quick installation and high torque application, reducing assembly time while ensuring a secure fit. With a partially threaded shank and Rockwell C32 hardness, it resists shear forces and vibration-induced loosening, making it ideal for heavy-duty equipment, bridge construction, and industrial frameworks where reliability and corrosion resistance are paramount. By meeting DIN 6914 and ISO 7412 specifications, it delivers consistent performance and compatibility across global projects.

Specification Summary & Compliance
