S-94831A641 7/16"-14 Flange Nuts

Key Features & Benefits at a Glance

• Vibration-resistant locking through serrated flange design prevents loosening under dynamic loads
• Enhanced corrosion protection with zinc-plated steel construction for extended service life
• Integrated flange distributes load over wider surface area, reducing material stress
• Precision Class 2B thread fit ensures smooth assembly and reliable engagement
• Coarse UNC threading provides rapid installation in industrial applications
• External hex drive allows for standard tool compatibility and high torque application
• Regulatory compliance with REACH and RoHS 3 standards for global market acceptance

Professional Applications & Engineering Value

This heavy-duty flange lock nut combines serrated locking technology with zinc-plated steel construction to solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and structural frameworks. The 15/16" flange diameter creates a larger bearing surface that distributes clamping force effectively, preventing surface damage while the serrations beneath the flange bite into mating surfaces to maintain clamp load under extreme vibration conditions. The 7/16"-14 UNC coarse thread configuration ensures quick installation and removal while maintaining Class 2B thread fit precision for consistent performance in high-vibration environments where secure fastening is paramount.

Specification Summary & Compliance

This flange lock nut features 7/16"-14 UNC coarse threading with Class 2B thread fit tolerances, 15/16" flange diameter, and external hex drive configuration. Manufactured from zinc-plated steel with serrated locking mechanism and right-hand thread orientation. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for restricted substances.
