An economy version of deluxe Fowler Gage Block Sets, featuring ±0.000050" (fifty millionths) accuracy and a very significant price savings.

Fowler "Economy/Workshop" grade Gage Block Sets are identical to standard sets in all respects, except for the wider range of tolerance which is more than adequate for a majority of shop needs.  Blocks are rectangular, constructed of the finest grade of high carbon/chrome steel, fully stress relieved, hardened to 65 RC, lapped and mirror polished to a very low micro-surface finish.  Blocks feature a low coefficient of thermal expansion, and they are carefully inspected for accurate size, parallelism and flatness.
