Key Features & Benefits at a Glance
- Superior vibration resistance with nylon insert locking that maintains secure fastening in high-motion environments
- Enhanced corrosion protection from black-oxide coated 18-8 stainless steel, ideal for harsh industrial conditions
- High-temperature performance with nylon insert rated up to 250°F, ensuring reliability in thermal cycling applications
- Quick installation and removal with standard external hex drive and coarse UNC threading for efficient assembly
- Distributed load bearing thanks to the 1.016" flange diameter, reducing surface damage and improving joint integrity
- Precise thread engagement with Class 2B fit, providing consistent clamping force and reducing cross-threading risks
- Regulatory compliance with REACH and RoHS 3 standards, meeting global environmental and safety requirements
Professional Applications & Engineering Value
This nylon insert lock flange nut combines the durability of black-oxide 18-8 stainless steel with engineered locking technology to solve critical industrial challenges. The integrated flange eliminates the need for separate washers, distributing clamp load over a wider area to prevent material deformation in assemblies like machinery frames, automotive components, and structural supports. Its coarse UNC thread ensures rapid installation even in low-visibility conditions, while the nylon insert provides consistent vibration resistance without galling or seizing—common issues in high-cycle equipment. With a 250°F temperature rating, it performs reliably in engine compartments, HVAC systems, and outdoor installations where thermal expansion and environmental exposure compromise standard fasteners.
Specification Summary & Compliance
Manufactured to precise dimensional standards including 1/2"-13 UNC coarse thread with Class 2B thread fit for consistent engagement. The nut features a 1.016" flange diameter and 0.14" flange thickness for optimal load distribution. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring adherence to international environmental and safety standards for industrial components.
