S-90949A135 1"-14 Flange Nuts

Key Features & Benefits at a Glance

• Vibration-resistant locking through distorted thread technology prevents loosening in high-stress environments
• Enhanced corrosion protection with black-phosphate steel coating extends service life in harsh conditions
• Superior load distribution from the 2 1/16" flange diameter reduces surface pressure and material stress
• High-strength performance with Grade G classification ensures reliable performance in demanding applications
• Precision fine threading (1"-14) provides superior clamping force and vibration resistance compared to coarse threads
• Easy installation and removal with standard external hex drive compatible with common wrench sizes
• Environmental compliance with RoHS 3 standards meets international regulatory requirements

Professional Applications & Engineering Value

This Grade G flange locknut delivers exceptional engineering value through its distorted thread locking mechanism that actively resists vibrational loosening in heavy machinery, automotive assemblies, and structural applications. The black-phosphate steel construction provides superior corrosion resistance while maintaining the mechanical properties required for high-stress environments. The 1"-14 fine thread configuration offers improved tension control and better resistance to vibrational loosening compared to coarse thread alternatives. The integrated 2 1/16" flange eliminates the need for separate washers, reducing assembly time and providing broader surface contact to prevent material damage. These features make this external hex locknut ideal for applications where vibration resistance, corrosion protection, and reliable locking performance are critical operational requirements.

Specification Summary & Compliance

This flange locknut features Class 2B thread fit tolerance for precise engagement and reliable performance. Manufactured to UNS thread standards with fine thread spacing (1"-14), the nut ensures compatibility with standard mating components. The product maintains RoHS 3 (2015/863/EU) compliance and meets Grade G strength classification requirements, providing assurance of material quality and environmental responsibility. The external hex drive (1 1/2" width) and right-hand thread direction follow industry-standard specifications for straightforward integration into existing assemblies.
