Fowler's Square Ceramic Gage Block Sets are manufactured to the same high precision as our rectangular sets. Zirconia Ceramic Gage Blocks are available in 36 and 81 piece sets and in two grades. Square in shape, they are constructed of high grade zirconia ceramic, lapped for high accuracy... and very competitively priced with steel gage blocks.
