Professional Applications & Engineering Value

This PTFE plastic hex nut delivers critical performance advantages in demanding industrial environments where metal fasteners fail. The high-temperature rating of 500°F makes it ideal for thermal processing equipment, chemical processing systems, and automotive applications where heat resistance is paramount. The Class 2B precision fine threading ensures secure fastening in high-vibration machinery while the corrosion-resistant properties of PTFE eliminate degradation from chemicals, moisture, and aggressive industrial atmospheres. The external hex drive facilitates efficient installation in confined spaces, reducing assembly time and maintenance costs. These UNF thread nuts provide reliable performance in plumbing, hydraulic systems, and precision instrumentation where consistent thread engagement is essential for leak prevention and operational safety.

Specification Summary & Compliance

This 3/8"-24 UNF hex nut features Class 2B thread fit per Unified National Fine standards, ensuring precise dimensional accuracy and reliable performance. The inch-system specification includes a standard 9/16" width across flats and 21/64" height for consistent tool engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance compliance for global industrial applications. The right-hand thread direction and fine thread spacing provide optimal clamping force distribution and vibration resistance in critical assemblies.
