Starrett Depth Gauges
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.

Starrett Depth Micrometers
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.

Starrett Depth Micrometers with Calibration Certificate
These micrometers come with a calibration certificate traceable to NIST that states they've passed a test for accuracy. Change out the steel extension rods supplied in 1" incremental lengths to measure the depth of holes, slots, shoulders, and projections. 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.
