Reach deep into small holes and slots for precise depth measurements. This gauge has a rod to measures the depth of recesses where the blade won’t fit. The blade has a hook which grabs the edge of an object for easy alignment. Markings are etched for wear resistance.

Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths. The thimble has a constant-force mechanism, so that once the spindle contacts the surface of the measured object, it will stop tightening. This ensures repeatable measurements and prevents over-tightening.

An LCD display helps you read depth measurements of drilled holes and machined slots. These gauges are often used for quality control in manufacturing plants and laboratories. Store data internally or use the SPC data output to connect to a computer or data processor. This allows you to analyze data and monitor measurements in real time. The zero-set button lets you start measuring at any point. With zero-position memory, also known as absolute (ABS) positioning, these gauges retain their measuring position when the scale is off. To save battery life, they turn off after 30 minutes of inactivity.

These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.

Protect Starrett depth gauges while storing and transporting them with these specially fitted cases.

The contact point is located on the back of this indicator, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements. A rugged design with few moving parts and highly sensitive, wear-resistant jeweled bearings give it a longer service life than other indicators. Rotate the dial face for viewing at multiple angles. The included tip adapter lets you use AGD-standard contact points that have 4-48 threads.

These indicators come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They have a balanced dial with positive values on one side of the zero and negative values on the other side for comparative measurements of a part's tolerance against a reference measurement. A spring-loaded plunger retracts and extends to measure objects. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles.

Also known as surface gauges, use these to scribe lines, transfer measurements, or as height and depth gauges. They have a V-groove base that can be used on round or flat surfaces.

Gauge pins can be pushed down for use against the edge of a surface plate or T-slot for linear work.

Half of the measurement scale on the dial face is highlighted yellow to make measurements easier to read. Also known as test indicators, these have a lever-style contact point that pivots as it comes into contact with a surface and a balanced dial with positive values on one side and negative values on the other side. They have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles. The ratcheting contact point can be adjusted to various angles.
