- Coarse UNC threading enables quick installation and resistance to cross-threading
Professional Applications & Engineering Value
This 8-32 UNC flange lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The distorted thread locking mechanism creates consistent interference fit that maintains clamp load despite continuous vibration, shock, and thermal cycling. Manufactured from cadmium yellow-chromate plated steel, these nuts provide exceptional corrosion resistance while meeting MS21042-08 military specifications for reliability in aerospace, automotive, and heavy equipment applications. The integrated flange design (0.29" diameter) eliminates washer requirements while providing superior bearing surface distribution, making these external hex flange nuts ideal for high-vibration environments where maintenance access is limited and fastener integrity cannot be compromised.
Specification Summary & Compliance
This flange lock nut features 8-32 UNC coarse threads with Class 3B thread fit for precision engagement, manufactured to MS21042-08 military specifications. Dimensions include 7/32" width, 3/16" height, 0.29" flange diameter, and 0.03" flange thickness. The right-hand thread direction and external hex drive provide standard installation compatibility. The cadmium yellow-chromate plating offers corrosion protection while maintaining compliance with industrial standards for reliable performance in critical fastening applications.
