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.
