Professional Applications & Engineering Value
This ceramic hex nut solves critical engineering challenges in extreme temperature applications where metal fasteners would fail. The 4-40 UNC coarse thread configuration combined with Class 2B thread fit ensures reliable performance in high-vibration environments while the external hex drive simplifies maintenance access. Ideal for furnace components, aerospace systems, semiconductor manufacturing equipment, and chemical processing applications, this nut maintains dimensional stability under thermal cycling that would cause conventional fasteners to degrade. The off-white ceramic material provides inherent resistance to oxidation and chemical attack, eliminating the need for protective coatings that can break down at elevated temperatures.
Specification Summary & Compliance
This 4-40 UNC hex nut features Class 2B thread fit for precise engagement, coarse thread spacing for vibration resistance, and right-hand threading following Unified National Coarse standards. Dimensions include 1/4" width and 3/32" height with standard hex profile. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility while meeting industrial quality requirements for extreme temperature applications.
