S-93083A104 10-32 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through serrated locking technology that bites into mating surfaces, preventing loosening under dynamic loads
• Enhanced load distribution with the 1/2" flange diameter, reducing surface pressure and preventing damage to assembled components
• Corrosion-resistant performance thanks to black-oxide steel construction, providing durable protection in various industrial environments
• Precise thread engagement with Class 2B thread fit ensuring reliable, consistent fastening in critical applications
• Easy installation and removal using standard wrench tools with the external hex drive design
• Secure fine thread locking with 10-32 UNF thread specification maintaining tension in high-vibration settings
• Regulatory compliance assurance meeting both REACH and RoHS 3 environmental standards for global manufacturing applications

Professional Applications & Engineering Value

This 10-32 UNF serrated flange locknut delivers exceptional engineering value in applications where vibration-induced loosening compromises assembly integrity. The black-oxide steel construction provides corrosion resistance while the serrated locking mechanism creates permanent friction against mating surfaces, eliminating the need for additional locking components. The 1/2" flange diameter distributes clamping force over a wider area, preventing surface damage in soft materials and reducing stress concentration. With fine thread spacing and Class 2B thread fit, this flange nut maintains precise tension in automotive, machinery, and electronic enclosures where reliability is critical. The combination of serrated locking technology and external hex drive makes it ideal for maintenance-intensive environments requiring repeated disassembly and reassembly.

Specification Summary & Compliance

This flange locknut features 10-32 UNF fine threads with Class 2B thread fit for consistent engagement and reliable performance. The external hex drive with standard profile accommodates common wrenching tools, while the 1/2" flange diameter and 0.03" thickness provide optimal load distribution. Manufacturing complies with UNF thread standards and includes full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring suitability for global industrial applications and restricted substance requirements.
