123Z-24 Starrett Master Vernier Calipers 24* / .001* Grad in Finished Wood Case

123Z-24

Ultimate example of slide caliper design. It is
more accurate, has the easiest reading vernier
style, is stronger and offered in much longer
lengths than other slide calipers.

Readability Features

• Long 50-division vernier scales permit
  half as many bar graduations as
  conventional single-vernier tools. These
  widely-spaced graduations make it easy
  to read to .001" or 0.02mm
• The open-face design of the slide allows
  both the inside and outside vernier scale
  on the same side, thus allowing both
  verniers to be read without turning the
  tool over
• Black lines and figures against the
  Starrett satin chrome finish make reading
  a pleasure, not an effort
• Screw-type adjusting nut allows for fine
  measuring adjustments and lock nut
  holds measurements

Long-Life and Accuracy Features

• Fine tool steel construction makes
  the jaws harder and longer-wearing
  than stainless tools. All tools through
  24" (600mm) also have hardened and
  stabilized bars.
• Hardened, ground and lapped measuring
  surfaces
• Machine divided graduations for accuracy
• The combination straight and angular
  ways on the master bar allow for positive
  alignment of graduations and easy
  adjustment of the flush-fitting verniers
• Sizes through 24" have divider points on
  the back side to accurately set dividers
  and trammels
• Tools with inch and millimeter
  graduations on the same bar have
  outside readings only. (Inside readings
  must be compensated for by adding the
  nib width to the indicated reading.)
• The longer length of the adjusting jaw
  slide provides a longer bearing surface
  on the master bar, ensuring squareness
  with the solid jaw and extra resistance to
  springing
• Tight, smoothly fitted slides for maximum
  accuracy and easy adjustment
