These dial indicators are used to measure small distances & angles, and translate them into rotational movement of the dial. They are available in graduations ranging from 0.00005 to 0.001 inches in the imperial system and 0.001 to 0.01 mm in the metric system.

JStarrett 649 Series spindle squares offer convenience & accuracy while tramming the head of vertical milling machines. These spindle squares are easier to use and more precise as compared to conventional methods of tramming using dial test indicators. They ensure perpendicularity and squareness between the work surface & spindle, and come fully assembled with two AGD Group 2 dial indicators. These devices feature solid steel construction with black oxide finish for corrosion resistance and long service life. Variants are available in graduations of 0.0005 and 0.001 inches.

Starrett dial drop indicators, also known as plunger-style dial indicators, come with a dial face attached to a stem with a contact point on the end. When the contact point meets the workpiece, the up-and-down motion of the plunger is increased on the graduated dial face.
Some of the major parts of dial indicators are a dial consolidated on the main scale, the plunger, locking screw or locknut, mini dial that indicates the number of revolutions and magnification mechanism.
The two basic types of indicator dials are balanced and continuous. To use one or the other is usually decided by the gauge and the range of the indicator. However, in general, if the resistances are reciprocal, like +/- 0.001 inches, the balanced dial is used.
Starrett dial indicators are one of the main measuring tools used in precision engine building. These dial indicators are suitable for measuring crankshaft thrust, deck clearances and other measurements that need the distance between two surfaces.
Starrett test indicators are quite distinct from dial indicators. The most notable difference is that dial indicators have plunger-type contacts. Whereas the test indicators feature lever-type contacts while they are also smaller and lighter in comparison to dial indicators.
Starrett has been manufacturing tools in the United States, having its headquarters in Athol, Massachusetts.
Starrett dial indicators usually range from 0.25 mm to 300 mm, with graduations of 0.001 mm to 0.01 mm (metric) or 0.00005 to 0.001 inches.
To make sure the indicator hand can move freely, it should be able to move to its total capacity and the zero ends of the scale in one fluid movement. Some of the guidelines are as follow
Lift the plunger and slip a 0.020-inch gauge block underneath. Drop the plunger onto the surface of the gauge block. Inspect that the indicator reads 0.020-inch. Then, lift and lower the plunger two more times to check that the dial indicator provides the same measurement in the exact spot constantly.
