1. The data in the table is not guaranteed and intended only as informational. Exposing ceramic fasteners to the same forces typically exerted on metal fasteners is not recommended and may result in catastrophic failure.

2. "Destructive Torque" is the average maximum torque on hex head bolts until failure.
