STARRETT Dial Indicators
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.

Features
- These indicators feature adjustable bezels for a positive grip and provide a balanced dial up to 4 inches.
- They come equipped with plain / jewelled bearings for low friction & superior precision and have satin chrome finish to ensure easy cleaning & corrosion resistance.
- These dial indicators feature a continuous reading dial that means the graduations decrease or increase in only one direction from the reference point.
- The pressure needed on the measuring head to secure zero reading must remain continuous over the complete range.
Working Mechanism
- Starrett dial indicators work on the mechanism that a little upward pressure on the spindle at the contact point is amplified through a system of levers and gears.
- These dial indicators have a round graduated dial and a contact point attached with a spiral or gear train so that the hand on the dial face reflects the portion of the movement of the contact point.
- They are used with a broad range of standard measuring equipment like dial box gauges, portal dial, hand gauges, dial depth gauges, diameter gauges and dial indicator snap gauges.
- They correspond to a spindle movement of 1 mm. The movement mechanism of the instrument is enclosed in a metal case for its safety. The large dial scale is graduated into 100 divisions and the indicator is set to zero using slip gauges.
Frequently Asked Questions
What is a dial drop indicator?
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.
What are the different parts of a Starrett dial indicator?
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.
What are the two basic types of dial indicators?
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.
What kind of measurements are Starrett dial indicators employed for?
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.
How are Starrett dial indicators different from dial test indicators?
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.
Where are Starrett dial indicators manufactured?
Starrett has been manufacturing tools in the United States, having its headquarters in Athol, Massachusetts.
What is the range of dial indicators?
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.
What are the guidelines for the proper use of Starrett dial indicators?
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
How do you adjust a Starrett dial indicator?
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.
