Any other head configurations are welcome and they are a custom order. The same sizes are available as above, but delivery will be approximately 4 weeks.

Nuts and washers are also available for each size listed above in either material.

Pitch diameter of male threads will not exceed the max allowable according to Class 2. Minimum allowable pitch diameter may be below that of Class 2. Conversely for female threads. Due to shrink factor variations in processing, stack-up tolerance cannot be controlled on the pitch. It is recommended not to engage more than 5-10 threads on any male fastener.

No warrantee with respect to torque strength and tensile strength is extended, nor implied. Ceramic materials are inherently brittle and display catastrophic failure mode if impacted, or stressed beyond the material's limit.
