Design Features

Silicon nitride ceramic bolts, also known as insulating ceramic screws and fasteners, possess several design features and excellent material 

properties, making them an ideal choice for high-end industrial applications.

Excellent Mechanical Strength and Wear Resistance

Silicon nitride possesses an elastic modulus of 290 GPa and a Vickers hardness of 1500 HV, providing exceptional wear resistance and 

mechanical stability, enabling the bolts to endure under high pressure and high load environments.

High Heat Resistance and Thermal Shock Resistance

With a maximum operating temperature of 1200℃ and a thermal shock stability coefficient of 500℃, these bolts maintain consistent 

performance in environments with extreme temperature fluctuations, making them suitable for high-temperature operating scenarios.

Excellent Insulation Properties

With very low dielectric loss and high electrical insulation strength, silicon nitride bolts prevent current leakage and short circuits in 

electronic and electrical equipment, ensuring equipment safety.

Chemical Stability and Corrosion Resistance

Silicon nitride is chemically stable and resistant to corrosion from a variety of chemicals, making it particularly suitable for use in chemical 

processing equipment.

Smooth Surface and Precision Manufacturing

The bolts have a very smooth surface finish, which helps reduce friction and wear during assembly, while precise thread machining ensures 

compatibility with conventional metal nuts or other fasteners.

Application areas

Silicon nitride ceramic bolts play an important role in many high-tech and demanding industrial fields:

Electronic Equipment

Used in the connection of sensitive electronic components requiring insulation or operation in high-temperature environments, such as in 

semiconductor manufacturing and electronic assembly.

Chemical Processing

Used in the assembly of chemical reactors and processing equipment, ensuring the long-term stability of connection points in corrosive 

environments.
