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

Short, narrow contacts allow these calipers to take hard-to-reach measurements, such as the dimensions of internal grooves and slots.

Detect variations in a range of hole diameters and depths.

Check for sizing errors in small slots and holes. These bore gauges are often used in precision manufacturing to test electronics and small-scale prototypes.

Test for size deviations across a range of hole diameters.

With a short stem, these gauges easily maneuver in shallow holes and are compact enough to slip into your pocket. Use them to check the diameter and roundness of a hole.

Measure the diameter of small holes, grooves, and recesses.

Measure the diameter of small holes, grooves, and recesses.

A different measuring range on each gauge makes these sets handy for checking a variety of hole sizes. Each gauge has spring-loaded contacts on the probe, which expand inside holes to measure diameter.

Spring-loaded contacts on the end of the probe expand inside holes, making these bore gauges versatile enough for general checks.

Position these gauges snugly within your bore to measure its diameter. Spring tension pushes the gauge’s two telescoping steel contacts against the walls of your bore.

Find the inside diameter of cylinders and rings.

With an LCD screen, these micrometers make it easy to read inside diameter measurements taken from cylinders and rings.

Reach into bores to measure the precise size and location of grooves.

Measure bore diameter directly. These gauges give you the actual diameter, unlike a dial bore gauge, which only shows the variation from a set measurement.

Whether a chamfered edge is in a screw hole or on the end of a rotary shaft, these gauges find its diameter. The calculated diameter displays on the LCD screen for quick readings.

Deep jaws and extra-long measuring ranges make measuring large material easier.

Take inside and outside measurements by moving the jaw along the ruler.

These calipers have a mechanism which allows you to make finer adjustments.

Protect sensitive electronics from damage while you take accurate measurements.

Carbide-tipped jaws provide greater wear resistance and longer life when measuring abrasive or very hard materials.

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

The pointed jaws on this caliper can fit into smaller spaces than standard calipers jaws.

Read your measurements easily on an LCD. Sets include a caliper, micrometer, and case.

These sets come with calibration certificates traceable to NIST that state the tools have passed a test for accuracy.

Read your measurements easily on an LCD. Sets include a Starrett caliper, micrometer, and case.

These sets come with calibration certificates traceable to NIST that state the tools have passed a test for accuracy.

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

Measure the depth of holes, slots, shoulders, and projections by changing out the steel extension rods supplied in 1" incremental lengths.

IP54 rated for limited protection from dust and splashing water.

Take depth measurements in dirty machining environments. These micrometers are rated IP65, so they seal out oil, water, and dust.

Confirm your depth micrometer is accurate. These gauges check your micrometer starts measuring at zero.

A true source of measurement, use these gauge blocks to calibrate measuring equipment, mark precise layouts, or position your fixture or machine components just right.

Use the Starrett gauge blocks in these sets individually or together to take precise measurements or calibrate your measuring tools. All have been laboratory calibrated and include NIST traceable certification with the tested measurements.
