The Alumina Socket Bolt is a ceramic material bolt within Goodfellow's wide range of bolts. Alumina, or aluminum oxide, is known for its excellent hardness, wear resistance and electrical insulation. This advanced ceramic material is available in multiple sizes and thread configurations to suit different fastening applications. With its lightweight yet rigid construction, alumina socket bolts are ideal for use in high temperature environments like automotive engines or industrial furnaces. Alumina bolts can also provide electrical isolation in electrical connectors or scientific instrumentation. With Goodfellow, engineers can select from multiple alumina bolt variations to meet their specific design needs.
