S-93474A236 M12 x 60 mm ISO 898-1, DIN 6921 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Superior tensile strength of 150,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Enhanced corrosion resistance from zinc yellow-chromate plating extends service life in harsh industrial environments, minimizing maintenance needs.
• High hardness rating (Rockwell C32) provides excellent wear resistance, maintaining structural integrity under repeated loads.
• Flanged hex head design eliminates the need for separate washers, speeding up assembly and providing a larger bearing surface for secure fastening.
• Class 10.9 strength grade guarantees consistent performance for heavy-duty applications, meeting rigorous industrial standards.
• Partially threaded shank allows for precise clamping force control, ideal for materials requiring vibration resistance.
• External hex drive enables easy installation with standard tools, reducing assembly time and labor costs.

Professional Applications & Engineering Value

Engineered for demanding environments, these M12 hex head screws combine Class 10.9 high tensile strength with a zinc yellow-chromate plated steel finish to combat corrosion in outdoor or chemically exposed settings. The flange design distributes load evenly, preventing surface damage and loosening under vibration—common in machinery, automotive frames, and structural steel assemblies. With a coarse thread pitch of 1.75mm, they provide quick engagement in brittle materials like cast iron, while the partial threading ensures optimal grip length for joint stability. Ideal for heavy-duty industrial applications, these screws deliver reliability where failure is not an option, backed by ISO standards for consistent quality.

Specification Summary & Compliance

This M12 x 1.75mm screw adheres to ISO 898-1 DIN 6921 specifications, with a Class 6g thread fit for precise tolerance. It is REACH (EC 1907/2006) compliant, ensuring safe use without hazardous substances, and features a 60mm length with a 26.6mm flange diameter for standardized installation. The metric coarse thread and external hex drive align with global engineering requirements, providing interoperability in multinational projects.
