S-93083A116 7/16"-14 Flange Nuts

Key Features & Benefits at a Glance

• Permanent vibration resistance through serrated locking technology that bites into mating surfaces to prevent loosening under dynamic loads
• Enhanced load distribution with 15/16" flange diameter that reduces surface pressure and prevents material damage
• Superior corrosion protection from black-oxide steel finish that provides durable resistance against rust and wear
• Reliable thread engagement with Class 2B thread fit ensuring consistent installation torque and secure fastening
• Industry-standard compatibility through UNC coarse threading that matches common industrial equipment and components
• Easy installation and removal with external hex drive design compatible with standard wrenching tools
• Environmental compliance assurance meeting both REACH and RoHS 3 standards for safe industrial use

Professional Applications & Engineering Value

This black-oxide steel flange lock nut delivers critical vibration resistance in demanding applications where joint integrity is paramount. The serrated locking mechanism creates permanent friction against bearing surfaces, eliminating the need for additional locking components in heavy machinery, automotive assemblies, and structural frameworks. The integrated 15/16" flange distributes clamp load over a wider area, preventing surface damage to softer materials while maintaining joint stability. Manufactured with UNC coarse threads and Class 2B thread fit, this fastener ensures reliable performance in high-vibration environments where standard nuts would fail, making it ideal for construction equipment, transportation systems, and industrial manufacturing applications requiring permanent, maintenance-free fastening solutions.

Specification Summary & Compliance

This flange lock nut features 7/16"-14 UNC coarse threads with Class 2B thread fit for consistent engagement and proper clearance. The external hex drive (11/16" width) and standard hex nut profile ensure compatibility with common installation tools. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, confirming the absence of restricted substances. The right-hand thread direction and serrated locking type provide reliable performance in accordance with industrial fastening specifications.
