S-93776A500 1/2"-13 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through serrated locking technology that prevents loosening under dynamic loads
• Enhanced load distribution with 1 1/32" flange diameter that reduces surface pressure and prevents material damage
• Excellent corrosion resistance from 18-8 stainless steel construction for long-term reliability in harsh environments
• Reliable thread engagement with Class 2B thread fit ensuring consistent performance and easy assembly
• Optimized installation efficiency through standard external hex drive design compatible with common tools
• Durability in demanding applications with coarse UNC threads that resist cross-threading and provide strong holding power
• Regulatory compliance assurance meeting both REACH and RoHS 3 environmental standards for global industrial use

Professional Applications & Engineering Value

This heavy-duty flange locknut addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and structural applications. The serrated locking mechanism beneath the flange creates permanent resistance to rotational forces, eliminating the need for secondary locking devices. Manufactured from 18-8 stainless steel, the nut maintains integrity in corrosive environments while the 1 1/32" flange diameter significantly increases bearing surface area, distributing clamp load effectively to prevent joint fatigue. The UNC coarse thread profile with Class 2B fit ensures reliable engagement even in high-vibration scenarios, making it ideal for equipment subjected to continuous dynamic stresses where maintenance access is limited.

Specification Summary & Compliance

This flange locknut features 1/2"-13 UNC coarse threads with Class 2B thread fit for consistent engagement and right-hand thread direction. The external hex drive with standard profile provides compatibility with common wrenching tools. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring regulatory compliance for industrial applications worldwide. Dimensions include 3/4" width, 29/64" height, and 0.15" flange thickness for precise engineering applications.
