  • Used as masters to calibrate measuring equipment and check linearity of comparators, micrometers, and calipers.
  • These ‘Tenth Step” gage sets have unlimited applications, such as quality control inspection, prototype work and production layout.
  • Inspectors select from the range of pins to find the size of a hole or slot.
  • These round masters simulate a cylindrical part which, unlike flat blocks, can detect uneven wear on the tips of micrometers and calipers.
  • The thin “line” of contact detects uneven face wear better than flat gage blocks with large contact area.
