S-90854A145 M6 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 or outdoor industrial environments.
• High hardness (Rockwell C32) provides excellent wear resistance, maintaining thread integrity through repeated assembly and disassembly.
• Coarse thread pitch (1mm) allows for quicker installation and better performance in materials prone to stripping or vibration.
• Fully threaded design offers consistent clamping force along the entire length, ideal for applications requiring uniform load distribution.
• External hex drive head enables easy installation with standard tools, reducing assembly time and labor costs.
• Precise Class 6h thread fit ensures smooth engagement with mating components, minimizing cross-threading and improving assembly reliability.

Professional Applications & Engineering Value

This M6 hex head screw is engineered to address critical challenges in industrial settings, such as vibration-induced loosening and environmental degradation. The Class 10.9 steel construction provides a robust solution for heavy machinery, automotive assemblies, and structural frameworks where high tensile strength is non-negotiable. Its zinc yellow-chromate plating offers a durable barrier against moisture and chemicals, significantly enhancing corrosion resistance in demanding applications. The coarse metric thread (1mm pitch) ensures secure fastening in softer materials or where rapid installation is essential, while compliance with ISO 4017/DIN 933 guarantees interoperability and reliability in global engineering projects. This screw delivers consistent performance, reducing maintenance cycles and downtime.

Specification Summary & Compliance

This fastener adheres to ISO 4017 (equivalent to DIN 933) for dimensional accuracy and thread profile. The metric coarse thread (M6 x 1mm) conforms to Class 6h tolerance, ensuring precise fit with nuts and tapped holes. Manufacturing follows standardized specifications for hex head screws, including full threading and right-hand thread direction. It meets common industry requirements for material and performance, though specific compliance with RoHS, REACH, or ASME should be verified per application needs.
