Important Information -Please Read

Alumina & zirconia (PSZ) fasteners

  1. 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 to 10 threads on any male fastener.
  2. No warranty with respect to torque strength and tensile strength is extended or implied. Ceramic materials are inherently brittle and display catastrophic failure if impacted or stressed beyond material limits.
