Professional Applications & Engineering Value

Engineered for high-temperature applications where metallic fasteners would fail, this alumina ceramic hex head screw maintains structural integrity in furnaces, aerospace components, and semiconductor manufacturing equipment. The off-white ceramic material provides excellent electrical insulation and chemical resistance, while the coarse UNC thread pattern with Class 2A fit ensures reliable performance despite thermal expansion cycles. The external hex drive allows for secure tool engagement in confined spaces, making these industrial ceramic fasteners ideal for maintaining critical assemblies in extreme environments where temperature fluctuations would compromise conventional fasteners.

Specification Summary & Compliance

This 2-56 UNC screw features precise Class 2A thread fit with coarse thread spacing, manufactured to inch system standards. The 3/8" length is fully threaded for maximum engagement. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for industrial applications requiring certified components.
