Professional Applications & Engineering Value
This alumina ceramic hex head screw is engineered to solve critical challenges in extreme-temperature and corrosive environments where metal fasteners would fail. Its high-purity alumina ceramic construction maintains structural integrity and dimensional stability at temperatures up to 3000°F, preventing thermal expansion issues and ensuring consistent performance in furnaces, kilns, and aerospace components. The 1/4"-20 UNC coarse thread and Class 2A thread fit facilitate quick, reliable installation in high-heat assemblies, while the external hex drive allows for secure torque application. Ideal for industrial heating systems, semiconductor manufacturing, and research equipment, this screw provides a durable, non-conductive alternative that resists oxidation and thermal shock, extending service life and reducing maintenance downtime.
Specification Summary & Compliance
This 1/4"-20 UNC hex head screw features a coarse thread with Class 2A thread fit for standard tolerance and easy assembly. Manufactured from high-grade alumina ceramic with an off-white finish, it is fully threaded and measures 1/2" in length. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
