Professional Applications & Engineering Value
Engineered for extreme conditions, these alumina ceramic hex head screws solve critical challenges in high-temperature and corrosive environments. The off-white alumina ceramic material offers superior thermal stability, maintaining structural integrity where metal fasteners would degrade or melt. This makes them ideal for furnace linings, semiconductor manufacturing equipment, and aerospace components. The UNC coarse thread and Class 2A fit ensure reliable fastening in applications subject to vibration and thermal cycling, while the external hex drive allows for straightforward installation with standard tools. By resisting oxidation and chemical attack, these screws extend service life and reduce maintenance costs in industrial heating systems and chemical processing plants.
Specification Summary & Compliance
This 1/4"-20 x 3/4" hex head screw features a coarse UNC thread with Class 2A thread fit for precise dimensional accuracy. It is manufactured from high-purity alumina ceramic and is fully threaded for maximum holding strength. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
