Key Features & Benefits at a Glance
- Superior vibration resistance through precision serrations that lock firmly in place, preventing loosening in high-stress environments.
- Enhanced load distribution with a 1 3/16" flange that acts as an integrated washer, reducing surface pressure and material fatigue.
- Reliable fine thread engagement with 9/16"-18 UNF Class 2B threads for precise, secure fastening in demanding applications.
- Durable corrosion protection from zinc plating, extending service life in industrial and outdoor settings.
- Easy installation and removal using standard external hex drive tools, saving time and labor costs.
- Compliance with environmental standards including REACH and RoHS 3, ensuring safe use in regulated industries.
- Right-hand thread design for standard assembly processes, improving compatibility and workflow efficiency.
Professional Applications & Engineering Value
This heavy-duty flange locknut is engineered to address critical challenges in industrial machinery, automotive assemblies, and structural frameworks where vibration-induced loosening can lead to equipment failure. The zinc-plated steel construction provides excellent corrosion resistance, while the serrated locking mechanism bites into mating surfaces to maintain clamp load under dynamic stresses. The integrated flange eliminates the need for separate washers, streamlining installation and reducing part counts in UNF fine thread applications. Ideal for high-vibration environments like powertrains, conveyor systems, and heavy equipment, this nut ensures long-term reliability and reduces maintenance downtime.
Specification Summary & Compliance
This flange locknut features Class 2B thread fit for consistent engagement and 9/16"-18 UNF fine threads meeting standardized dimensions. Manufactured from zinc-plated steel with a 1 3/16" flange diameter and 7/8" width, it complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations for hazardous substance restrictions, ensuring suitability for global industrial supply chains.
