Readability Features
- Long 50-division vernier scales, made popular by Starrett. This feature permits just half as many bar graduations as conventional single-vernier tools. These widely-spaced graduations make possible easy reading to .001" or 0.02 mm without requiring a magnifying glass
- Flush fitting of the vernier scales to the main scale means that these are in the same plane, which eliminates parallax. Vernier scales are adjustable
- 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
- Lock nut to hold measurements
Long-Life and Accuracy Features
- These tools are made of the finest tool steel. This makes the jaws harder and longer-wearing than stainless tools. All tools through 24" (600 mm) also have hardened and stabilized bars
- Measuring surfaces are hardened, ground and lapped to close limits
- All graduations are machine divided for accuracy, not photo-engraved. They are also deeper and sharper
- 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 as needed
- Tools with inch and millimeter graduations on the same bar have outside readings only.
