S-91294A549 M8 x 90 mm DIN 7991, ISO 10642 Alloy Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Exceptional strength and reliability with Class 10.9 grade, ensuring high load-bearing capacity and resistance to shear and fatigue in demanding applications.
• Superior corrosion resistance thanks to the black-oxide coating on alloy steel, extending service life in harsh industrial environments.
• Precise and secure fastening with M8 coarse thread (1.25mm pitch) and Class 6g fit, providing excellent grip and vibration resistance.
• Efficient installation and removal using the 5mm hex drive, allowing for high torque application without slippage.
• Flush surface finish with a standard 90° flat head profile, ideal for applications where a smooth, unobtrusive fastener head is required.
• Full threading along the 90mm length offers maximum engagement and holding power across the entire fastener.
• Compliance with international standards including DIN 7991/ISO 10642, ensuring consistent quality and interoperability.

Professional Applications & Engineering Value

This M8 flat head screw is engineered to address critical challenges in industrial assembly, machinery, and structural applications. The black-oxide alloy steel construction, combined with a Class 10.9 strength rating (120,000 psi tensile strength, Rockwell C32 hardness), provides exceptional durability against dynamic loads and environmental stressors. The fully threaded coarse pitch design ensures rapid installation and reliable clamping force, reducing assembly time while maintaining joint integrity. Its hex drive facilitates easy torque application in confined spaces, making it ideal for automotive, construction, and heavy equipment where high-strength fasteners are essential for safety and performance. The flush flat head minimizes protrusion, preventing snagging and enhancing aesthetic appeal in finished products.
