    Matched within tenths
  

*by E***G on Reviewed in the United States on September 11, 2022*

These blocks are nicely ground and within a few tenths (.0001) on size (2", 3", 4") against my Jo block gauges and they are matched to each other within a few tenths.Five of the holes on the 3 by 5 face are threaded 3/8-16 thru.
