S-93474A219 M8 x 35 mm ISO 898-1, DIN 6921 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 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 rating (Rockwell C32) provides excellent wear resistance and durability under repetitive loads.
• Integrated flange design eliminates the need for separate washers, simplifying assembly and improving joint stability.
• Precision Class 6g thread fit ensures smooth installation and secure fastening with standard metric nuts.
• Partially threaded shank allows for controlled clamping force and prevents thread damage in blind holes.
• External hex drive compatibility enables quick installation with common tools, reducing assembly time and labor costs.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M8 hex head screws combine Class 10.9 strength with zinc yellow-chromate plating to address critical challenges in machinery assembly, automotive components, and structural frameworks. The partially threaded design prevents cross-threading in deep tapped holes while maintaining consistent clamping pressure. With 150,000 psi tensile strength and Rockwell C32 hardness, they withstand vibration and dynamic loads in heavy equipment. The integrated flange distributes load evenly, reducing surface pressure and preventing material deformation. These metric fasteners are ideal for applications requiring corrosion resistance without compromising mechanical integrity, making them suitable for outdoor enclosures, conveyor systems, and precision manufacturing equipment where reliability is paramount.

Specification Summary & Compliance
