Dimensions Per ASME B18.2.4.1M-2002 (R2007)

Material Properties Which is the best choice for your application?

Torque Values for applications dependent on specific torque or preload requirements.

Threads The 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 variances, the stack up tolerance cannot be controlled on the pitch. It is recommended that you not engage more than 5 threads on any male fastener.

Notice Ceramic materials are inherently brittle and display catastrophic failure if impacted or stressed beyond material limits.
