Key Features & Benefits at a Glance
- Superior vibration resistance through distorted top lock threads that maintain secure fastening under dynamic loads
- Enhanced anti-rotation performance with serrated flange surface that bites into mating surfaces
- Excellent corrosion resistance provided by 18-8 stainless steel construction for long service life
- Reliable installation precision with Class 2B thread fit ensuring consistent engagement
- Reduced assembly time with integrated flange eliminating the need for separate washers
- Secure locking action through distorted thread design that resists loosening in high-vibration environments
- Environmental compliance meeting both RoHS 3 and REACH standards for industrial applications
Professional Applications & Engineering Value
This 18-8 stainless steel flange lock nut delivers exceptional engineering value in demanding industrial environments where vibration-induced loosening compromises safety and performance. The combination of distorted thread technology and serrated flange surface creates a dual-locking mechanism that maintains clamp load integrity in machinery, automotive assemblies, and structural applications. The UNC coarse thread profile with Class 2B fit ensures reliable engagement with mating components while the integrated flange distributes load evenly across surfaces. Manufactured from corrosion-resistant 18-8 stainless steel, this external hex flange nut provides lasting performance in harsh operating conditions, making it ideal for OEM equipment, maintenance operations, and assembly lines where vibration resistance is critical.
Specification Summary & Compliance
This heavy-duty 1/2"-13 UNC flange lock nut features precision Class 2B thread fit with coarse thread spacing and right-hand thread direction. The nut maintains dimensional accuracy with a flange diameter of 1.031" and height of 29/64". Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, this fastener meets rigorous environmental and safety requirements for industrial applications worldwide.
