A superb combination of corrosion resistance, temperature stability and non-conductivity

• Exceptional temperature resistance up to 3000°F (1650°C)
• Outstanding corrosion resistance to acids, solvents, salts, and organics
• Excellent electrical & thermal insulator
• High purity
• Ceramic alumina socket head cap screw features and benefits
• Alumina ceramic datasheet

Alumina ceramic socket head cap screws are one of the most thermally resistant screws available. Due to their outstanding thermal resistance, alumina ceramic screws are geared for the most demanding high temperature applications. Alumina ceramic socket head cap screws also have outstanding corrosion resistance and are highly chemically resistant to acids, solvents, and salts. Additionally, alumina ceramic socket head cap screws find many uses in high voltage applications due to their non-conductive electrical properties.

Alumina ceramic socket head cap screws are available in both metric and standard sizes. Please contact us if you have any questions about the properties or availability of our ceramic socket head cap screws.

Socket head cap screws made from customer specified ceramic grades or custom dimensions are available upon request.

Screw Types: Flat Head Screws, Hex Cap Screws, Pan Head Screws, Set Screws, Socket Head Cap Screws

Ceramic Alumina Socket Head Cap Screws

When it comes to ceramic alumina socket head cap screws, it’s all about clearance. These screws are the best choice for applications with limited installation access or clearance. Yet if you have an application with a lot of debris, you may want to select a ceramic alumina hex head bolt or hex head cap screw, as they don’t have a socket drive which could get clogged.

Advantages:

• Ideal for applications with limited access as they require very little clearance around the fastener.
• Socket head cap screws can be used in locations where externally wrenched fasteners aren't desirable.
• Weight reduction on application as ceramic alumina socket head cap screws are smaller – being that the cylindrical heads of socket screws need less space than hex heads and require no additional wrench space.
• Also known for safety, reliability and economy.

Common Ceramic Grades

Alumina 99.8%

Alumina ceramic or Aluminum oxide (Al₂0₃) is the most common grade of alumina ceramics and is designated as being 99.8% pure. Alumina is most known for high temperature stability and has a usable temperature limit of 3000°F (1650°C). Alumin has the greatest balance of economy, mechanical and thermal properties.

Various other compositions of alumina ceramic are available upon request.
