Important Information -Please Read

Alumina & zirconia (PSZ) fasteners

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.
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.

Hex Head Fasteners

Hex head metric sizes M5 and larger & ANSI hex head sizes 6-32 and larger will have a washer head face. Hex head metric sizes M4 and smaller & ANSI hex head sizes 5-40 and smaller will not have the washer head face.
