S-90854A229 M12 x 35 mm ISO 4017, DIN 933 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength with Class 10.9 rating (150,000 psi) ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc yellow-chromate plating extends service life in harsh industrial environments, minimizing maintenance needs.
• High hardness (Rockwell C32) provides excellent wear resistance, maintaining thread integrity during repeated assembly and disassembly.
• Full threading along the entire 35mm length offers consistent grip and load distribution, enhancing joint stability in heavy-duty assemblies.
• Precision Class 6h thread fit with coarse 1.75mm pitch ensures easy installation and secure fastening, reducing assembly time and errors.
• External hex drive design allows for high torque application with standard tools, facilitating quick and secure installations in confined spaces.
• Compliance with ISO 4017/DIN 933 standards guarantees dimensional accuracy and interchangeability, ensuring compatibility with global engineering specifications.

Professional Applications & Engineering Value

Engineered for demanding environments, these M12 hex head screws deliver robust performance in machinery, structural steel connections, and automotive assemblies where vibration and dynamic loads are common. The Class 10.9 steel construction provides high tensile strength to prevent stripping under extreme forces, while the zinc yellow-chromate plating offers a protective barrier against oxidation and chemical exposure, crucial for outdoor or humid settings. With a coarse thread pitch of 1.75mm, these fully threaded metric screws ensure rapid engagement and reduced cross-threading risks, making them ideal for time-sensitive industrial maintenance and production lines. Their compliance with international standards like ISO 4017 ensures seamless integration into existing systems, supporting efficient B2B procurement and supply chain consistency.
