Key Features & Benefits at a Glance
- Superior vibration resistance through integrated serrations that bite into mating surfaces, preventing loosening under dynamic loads
- Enhanced load distribution with 26mm flange diameter that reduces surface pressure and prevents material damage
- Excellent corrosion resistance with 18-8 stainless steel construction suitable for harsh industrial environments
- Reliable thread engagement with Class 6H thread fit ensuring precise mating with corresponding bolts
- Quick installation using standard 18mm external hex drive compatible with common wrench tools
- Permanent locking performance through serrated flange design that maintains clamping force without requiring additional locking elements
- Regulatory compliance meeting both RoHS 3 and REACH environmental standards for safe industrial use
Professional Applications & Engineering Value
This M12 x 1.75 serrated flange lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant safety and maintenance concerns. The 18-8 stainless steel construction provides reliable corrosion resistance in demanding environments, while the integrated serrations create a permanent locking mechanism that eliminates the need for secondary locking devices. Manufactured to DIN 6923 specifications, these metric hex nuts feature a coarse thread pitch that enables rapid assembly in automotive chassis components, heavy machinery, and industrial equipment. The combination of external hex drive and Class 6H thread fit ensures consistent torque application and reliable performance in high-vibration applications where traditional fasteners would fail.
Specification Summary & Compliance
This flange lock nut features M12 x 1.75 mm coarse metric thread with Class 6H tolerance for precise fitment. The nut conforms to DIN 6923 manufacturing standards, ensuring dimensional accuracy with 26mm flange diameter, 2.19mm flange thickness, and 18mm hex width. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use across various industrial sectors without restriction.
