S-90477A119 M6 Flange Nuts

Key Features & Benefits at a Glance

• Superior load distribution thanks to the integrated 15.9mm flange, which acts like a built-in washer to protect surfaces and prevent loosening under vibration.
• Enhanced corrosion resistance from the black-oxide steel finish, providing a durable protective layer for long-term reliability in demanding industrial environments.
• Precise and reliable fit with a Class 6H thread tolerance, ensuring consistent engagement and secure fastening with compatible M6 bolts.
• Quick and easy installation with a 13mm external hex drive, allowing for high-torque application using standard wrenches for efficient assembly.
• Robust rotating performance designed for applications involving movement, maintaining integrity and clamp force where other nuts might fail.
• Cost-effective assembly by combining a nut and washer into a single component, reducing part count and speeding up production lines.
• Compliant for global use by meeting RoHS 3 standards, ensuring the material is suitable for regulated industries and international supply chains.

Professional Applications & Engineering Value

This M6 flange nut is engineered to solve common fastening challenges in industrial applications where vibration, dynamic loads, and corrosion are concerns. The black-oxide steel construction provides a robust barrier against rust, extending service life in machinery, automotive assemblies, and outdoor equipment. The integrated 15.9mm flange distributes clamping force over a wider area, reducing point stress and preventing damage to softer materials. With its Class 6H precision thread and coarse 1mm pitch, it offers rapid installation and high resistance to loosening, making it ideal for rotating components and high-vibration environments. The 13mm external hex drive ensures it can be securely tightened with common tools, streamlining maintenance and assembly processes for engineers and technicians.

Specification Summary & Compliance

This metric flange nut features an M6 x 1mm coarse thread with a Class 6H thread fit per ISO standards, ensuring dimensional accuracy and reliable performance. The flange is constructed from steel with a diameter of 15.9mm and a thickness of 3.2mm. The product is manufactured to be RoHS 3 (2015/863/EU) compliant under exemption 6(a) for lead as an alloying element in steel, confirming its suitability for use in regulated industrial and electronic applications.
