S-97400A135 M3 DIN 6923 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance with serrated locking teeth that bite into mating surfaces to prevent loosening under dynamic loads
• Enhanced load distribution through the integrated 8mm flange that reduces surface pressure and prevents material damage
• Exceptional corrosion resistance provided by 18-8 stainless steel construction for long-term reliability in harsh environments
• Precision threading with Class 6H fit and M3 x 0.5mm coarse pitch for quick assembly and consistent performance
• Standard external hex drive enables easy installation with common tools while maintaining secure fastening
• Regulatory compliance with REACH and RoHS 3 standards ensures environmental responsibility and material safety
• DIN 6923 certification guarantees dimensional accuracy and mechanical properties for industrial applications

Professional Applications & Engineering Value

This M3 metric flange nut combines the anti-vibration properties of serrated locking technology with the load-spreading benefits of an integrated flange, making it ideal for applications where vibration-induced loosening is a concern. The 18-8 stainless steel construction provides excellent corrosion resistance for outdoor equipment, automotive components, and industrial machinery exposed to moisture or chemicals. The 8mm flange diameter significantly increases the bearing surface area, reducing the risk of surface damage to softer materials while maintaining clamping force. Engineered to DIN 6923 standards with Class 6H thread fit, this external hex locknut delivers reliable performance in high-vibration environments where traditional fasteners might fail, ensuring long-term assembly integrity without the need for additional locking devices.

Specification Summary & Compliance

This flange lock nut features M3 x 0.5mm coarse metric thread with Class 6H precision tolerance and right-hand thread direction. Manufactured according to DIN 6923 specifications, it includes an 8mm flange diameter and 0.7mm flange thickness for optimal load distribution. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe and sustainable manufacturing practices. The external hex drive style (5.5mm width) and 4mm height provide standard tool compatibility while maintaining the mechanical integrity required for industrial applications.
