Professional Applications & Engineering Value
This 12-24 nylon insert locknut delivers critical vibration-resistant performance for demanding industrial applications where secure fastening is paramount. Engineered with 316 stainless steel, it provides exceptional corrosion resistance in challenging environments including chemical processing, marine, and food equipment. The nylon insert locking mechanism creates consistent friction against the mating bolt's UNC coarse threads, preventing loosening under dynamic loads while allowing for reusable installation. The external hex drive ensures compatibility with standard tools, streamlining maintenance procedures. With its Class 2B thread fit and temperature resistance up to 220°F, this locknut solves common industrial challenges of thermal cycling, vibration-induced failure, and corrosive degradation.
Specification Summary & Compliance
This locknut features 12-24 UNC coarse threading with Class 2B thread fit for proper engagement and consistent performance. The right-hand thread direction and standard hex profile (7/16" width, 5/16" height) ensure compatibility with industry standards. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making it suitable for regulated applications requiring documented material transparency and restriction compliance.
