S-91094A124 1"-14 Flange Nuts

Key Features & Benefits at a Glance

• Exceptional load distribution with a 2 1/16" flange diameter that reduces surface pressure and prevents damage to assembled materials
• Superior vibration resistance due to the extra fine 1"-14 thread pitch, maintaining clamp force in high-stress dynamic applications
• High tensile strength and reliability from Grade 8 steel construction, suitable for critical, heavy-duty industrial assemblies
• Precise and secure threading with Class 2B fit, ensuring smooth engagement and consistent performance with mating components
• Easy installation and removal using standard tools thanks to the external hex drive and standard hex nut profile
• Enhanced durability and corrosion resistance from quality steel material, extending service life in demanding environments
• Compliance with international environmental standards including REACH and RoHS 3, making it suitable for global supply chains

Professional Applications & Engineering Value

This Grade 8 steel flange nut is engineered to address common challenges in heavy machinery, automotive, and structural applications where vibration loosening and high clamp loads are concerns. The 1"-14 extra fine thread provides more threads per inch, significantly improving resistance to shock and vibration compared to coarse threads. The integrated flange acts as a built-in washer, distributing load over a wider area (2 1/16" diameter) to prevent surface damage and reduce the need for additional components. Made from high-strength steel and featuring a Class 2B thread fit, it ensures reliable, precise fastening in industrial applications requiring repeatable disassembly and reassembly without thread wear. Its external hex drive allows for efficient torque application, making it ideal for automated assembly lines and maintenance operations.

Specification Summary & Compliance

This flange nut conforms to UNS thread standards with a 1"-14 extra fine thread and Class 2B thread fit for consistent dimensional accuracy. It meets Grade 8 strength classification, ensuring high mechanical performance. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, supporting use in regulated industries and global markets.
