S-91290A606 M12 x 180 mm DIN 912, ISO 4762 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress industrial applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-oxide coating extends service life in harsh environments, minimizing maintenance and replacement costs.
• High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity and drive engagement over repeated use.
• Precision thread fit (Class 5g6g) offers consistent assembly and secure fastening, reducing the likelihood of loosening under vibration.
• Partially threaded design allows for controlled clamping force and easier alignment in assemblies, improving installation efficiency.
• Standard hex socket drive (10 mm) enables high-torque application with common tools, facilitating quick and secure installations.
• Compliance with international standards (DIN 912/ISO 4762) ensures interchangeability and reliability in global engineering projects.

Professional Applications & Engineering Value

This M12 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive, and construction sectors where high tensile strength and durability are paramount. The black-oxide alloy steel construction combats rust and wear in demanding environments, while the coarse thread pitch (1.75 mm) ensures rapid assembly and strong holding power in materials like steel and cast iron. With a partially threaded rod type, it provides optimal grip in tapped holes or with nuts, reducing stress concentration and preventing joint failure. Ideal for applications requiring precision metric fasteners that meet rigorous DIN 912 and ISO 4762 specifications, this screw delivers consistent performance in high-vibration settings, enhancing equipment longevity and operational safety.

Specification Summary & Compliance

This product adheres to precise metric dimensions including an M12 thread size with 1.75 mm pitch, 180 mm length, and 36 mm minimum thread length, manufactured to Class 5g6g thread fit for accurate engagement. It conforms to DIN 912 and ISO 4762 standards for socket head cap screws, ensuring dimensional consistency and mechanical properties. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance control in industrial use.
