S-91343A107 M5 DIN 6923 Flange Nuts

Key Features & Benefits at a Glance

• Enhanced vibration resistance with serrated locking design that prevents loosening under dynamic loads
• Superior corrosion protection from 316 stainless steel construction, ideal for harsh industrial environments
• Integrated flange distributes pressure across wider surface area (11.8mm diameter) to prevent material damage
• Maximum torque application through external hex drive design for secure fastening in high-stress applications
• Precision thread engagement with Class 6H fit ensuring reliable performance in metric coarse thread assemblies
• Reduced assembly time with combined flange and locking functions in a single component
• Compliance with industry standards including DIN 6923 for consistent quality and interchangeability

Professional Applications & Engineering Value

This M5 serrated flange locknut delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The 316 stainless steel construction provides exceptional durability in chemical processing, marine, and automotive applications where exposure to moisture and corrosive elements is common. The integrated flange design eliminates the need for separate washers while providing superior load distribution, preventing surface damage to connected materials. The serrated locking mechanism beneath the flange creates permanent friction against mating surfaces, maintaining clamp force in high-vibration environments like machinery, engine components, and transportation equipment. Manufactured to DIN 6923 standards with metric coarse threading (M5x0.8mm), these nuts ensure precise fit and reliable performance in industrial fastening systems.

Specification Summary & Compliance

This flange locknut features M5 metric coarse threading with 0.8mm pitch and Class 6H thread fit per ISO standards, ensuring precise engagement and consistent performance. Manufactured in compliance with DIN 6923 specifications, the nut includes an 11.8mm flange diameter, 1mm flange thickness, and standard hex profile (8mm width). The product is RoHS 3 (2015/863/EU) compliant and made from 316 stainless steel for corrosion resistance in demanding industrial applications.
