We started making the original ZZ back in 1965 and our competition has tried, but can’t copy the quality of these affordable pin gage sets. We now have taken the extra step for the better English Class Z Pin Gages Sets & Libraries. Introducing the MEYER Z. A closer tolerance (.0001), more accurate and better for your needs. We have done it again. We’ve made a better pin gage that no other has attempted with the same great features listed below.
See for yourself, below is a comparison of the Class ZZ and the Class Z gage pin specifications.
