Preet,
A Class ZZ tolerance for the diameter range .006 - .825 is .0002" (.005MM). Deltronic makes Class X Plus tolerance, for the diameter range .006 - .825 is .000040" (.001mm). The suggested tolerance for your product is Class Y (.000070"). This is based on the 10% rule, that the gages may not use more than 10% of the total product tolerance.
See our free Tolerance Calculator & Tolerance chart from ASME B89.1.5 at http://www.vermontgage.com/tech/archive/chart.html. We would not suggest using Class ZZ gages for this product. We do Stock Class X gages.
Thanks,
