Key Features & Benefits at a Glance

  • Superior vibration resistance with nylon insert locking that maintains secure fastening even under continuous motion and shock loads
  • Enhanced load distribution thanks to the 0.49" flange diameter, reducing surface pressure and preventing material damage
  • Excellent corrosion resistance from 18-8 stainless steel construction, ideal for harsh or outdoor industrial environments
  • Reliable high-temperature performance with nylon insert rated up to 250°F, ensuring locking integrity in demanding applications
  • Wide compatibility with UNC coarse 10-24 threads and Class 2B fit, providing consistent engagement with standard bolts
  • Easy installation and removal using standard 3/8" external hex drive tools, saving time on assembly lines
  • Environmental and regulatory compliance with RoHS 3 and REACH standards, meeting global safety and sustainability requirements

Professional Applications & Engineering Value

This 10-24 nylon insert locknut combines the stability of a flange nut with the security of a locking mechanism to solve critical industrial challenges. The 18-8 stainless steel body resists corrosion in chemical, marine, or high-moisture settings, while the nylon insert effectively dampens vibrations in machinery, automotive, and HVAC systems—preventing loosening that leads to equipment failure. Its UNC coarse thread and Class 2B fit ensure quick, precise assembly with common 10-24 threaded fasteners, reducing installation errors. The integrated flange spreads clamping force over a wider area, protecting soft materials and maintaining joint integrity under dynamic loads, making it a go-to for vibration-resistant and corrosion-proof applications.

Specification Summary & Compliance

This flange locknut features a 10-24 UNC coarse thread with Class 2B tolerance for consistent fit, and is manufactured from 18-8 stainless steel with a 0.49" flange diameter and 3/8" external hex drive. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
