Alumina Hexagonal Bolt - Q5

Details

SKU: 1000022457 Product Code: AL60-BT-000120
Alumina Hexagonal Bolt combines the exceptional hardness, wear resistance, and corrosion immunity of high-purity alumina ceramics with the functional geometry of a hexagonal head for secure fastening. Its excellent dielectric strength and thermal stability allow reliable performance in high-voltage assemblies, vacuum systems, and chemically aggressive environments. Commonly used in semiconductor manufacturing equipment, analytical instrumentation, aerospace systems, and chemical processing setups, these bolts provide robust fastening where metallic fasteners would fail due to corrosion or electrical conductivity. Specific uses include securing components in plasma etching chambers, supporting insulating fixtures in cryogenic or high-temperature furnaces, and assembling structures exposed to acids, alkalis, or reactive gases. In research and innovation, alumina hexagonal bolts play a pivotal role in developing high-reliability electrical, thermal, and structural interfaces under extreme conditions. Their combination of structural integrity and multifunctional resistance ensures lasting value in both scientific and industrial contexts.
