Professional Applications & Engineering Value

This fiberglass hex nut delivers critical advantages in demanding industrial settings where metal fasteners fail. Its non-conductive and corrosion-resistant properties make it perfect for electrical enclosures, chemical processing equipment, and marine applications. The UNC coarse thread design provides faster assembly and superior vibration resistance compared to fine threads, while the Class 2B thread fit ensures consistent engagement without galling. With a maximum temperature rating of 190°F and RoHS 3 compliance, this nut solves corrosion, conductivity, and environmental compliance challenges in OEM manufacturing and maintenance operations.

Specification Summary & Compliance

This hex nut features 1/2"-13 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy. The standard hex profile measures 3/4" width and 7/16" height with right-hand threading. Manufactured from gray fiberglass for consistent performance, it is RoHS 3 (2015/863/EU) compliant, meeting strict environmental regulations for industrial components.
