A superb corrosion resistance, temperature stability and non-conductivity

• Exceptional temperature resistance up to 2100°C (3800°F) 
• Outstanding corrosion resistance to acids, solvents, salts, and organics
• Excellent electrical & thermal insulator
• High purity
• Zirconia pan head screw features and benefits
• Zirconia ceramic datasheet

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

Zirconia ceramic pan head 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 screws.

Pan head 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 

Zirconia Pan Head Screw Features and Benefits

Pan head screws are flat on top and rounded on the sides. Zirconia pan head screws are ideal for:

• Small diameter fasteners – especially when the fastener size needed is too small for a wrench.
• When phillips or slotted drivers are desired. For many high strength specialty alloys, only slotted drives are available.
• Low torque applications because the drivers don’t offer as much force as a wrench.
• Large diameter head provides more clamping area.

How Are They Different from Button Head Screws?
Zirconia ceramic pan head and button head screws have very similar profiles however, button head screws allow for a hex socket driver whereas pan head screws do not.

Common Ceramic Grades

Zirconia YSZ

Zirconia ceramic or Zirconium Oxide (ZrO₂) is one of the most temperture stable materials available having a usable temperature range up to 3812°F (2100°C) and melting point at 4900°F (2700°C). This material is stabelized with yittria to prevent cracking and therefore designated as Yittria Stabilized Zirconia (YSZ). This grade is stronger, tougher and more thermally resistant than alumina. 

Other grades are available upon request.
