The Starrett 123Z-48 Master Vernier Slide Caliper has half as many bar graduations as conventional single-vernier tools, making them easy to read. Machine-divided graduations, tight, smoothly fitted slides, and no glare satin chrome finish give it an attractive appearance. Plus, the long 50-division vernier scales offer even more precision.
With the open-face design, the 123Z-48 allows you to see what you’re doing without getting in your way. Lastly, the screw-type adjusting nut allows for fine-measuring adjustments, and lock nut holds measurements.
- 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
