Ultra-High-Temperature Ceramic Washers
 |
Our most heat-resistant washers, even at blistering temperatures up to 3000° F. They distribute pressure evenly under nuts and screws in industrial furnaces, kilns, and other extreme-temperature environments. Ceramic may crack or dent if subjected to hard bumps, however, so these washers are not recommended for high-vibration applications.
Material Certificate—Washers include a report with a traceable lot number.

Extra-High-Temperature Ceramic—Our most heat-resistant washers and the best electrical insulators. These won't melt or become brittle at blistering temperatures up to 1,700° F, making them perfect for ovens, kilns, and furnaces. Ceramic may crack or dent if subjected to hard bumps, however, so these washers are not recommended for high-vibration applications.

Insulating Cup Washers
 |
Cover screw heads or nuts to block electrical current and prevent short circuits. These washers isolate fasteners from sensitive surface-mounted components, such as capacitators and transistors on printed circuit boards. They also extend the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.

These won't melt or become brittle at blistering temperatures up to 1,700° F, making them perfect for ovens, kilns, and furnaces.
