Professional Applications & Engineering Value
This nylon insert lock flange nut combines multiple engineering solutions for demanding industrial applications. The 18-8 stainless steel construction provides exceptional corrosion resistance in chemical processing, marine, and outdoor environments, while the nylon insert locking mechanism effectively counters vibration-induced loosening in machinery, automotive assemblies, and structural frameworks. The integrated 1.07" flange eliminates the need for separate washers, distributing clamp load over a wider area to prevent surface damage to softer materials. With UNC coarse threads and Class 2B fit, this fastener ensures reliable engagement in high-vibration equipment, transportation systems, and heavy machinery where vibration resistance and thermal stability up to 250°F are critical performance requirements.
Specification Summary & Compliance
This flange nut features 1/2"-13 UNC coarse threads with Class 2B thread fit for precise dimensional accuracy. The external hex drive design provides standard tool compatibility, while the right-hand thread direction ensures conventional installation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance compliance for industrial applications worldwide.
