Measure the outside diameter of small round- and hex-shaped objects such as rods, drill bits, bolts, and tubing with this pocket-size tool.

With a calibration certificate traceable to NIST that says they've passed a test for accuracy, you can trust these gauges to confirm if your object's outer diameter is within tolerance. They're also known as snap gauges because they snap onto rods, shafts, and other cylindrical objects.

Create and check angles with these precision-ground blocks. Each block is labeled with its angle.

Vital for dimensional quality control, these gauge blocks are often used for precision layout, machine setup, and producing close-tolerance dies and fixtures.

These sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

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.

Measure the inside diameter of cylinders and rings.

Measure a variety of hole diameters. These sets include gauges that use spring tension to expand the probe’s contacts inside of bores.

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

Inspect a variety of hole sizes with the gauges in these sets. Each has spring-loaded contacts on the probe, which expand inside holes to measure diameter.

Keep over two dozen different ball diameters on hand to check bore sizes or use as go/no-go gauges.

Use these gauges to measure the inside diameter of holes and cylindrical bores, as well as identify out-of-roundness problems.

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

These calipers have deep jaws for measuring large-diameter objects, such as pipes, poles, and logs.

Move the jaw along the ruler to take inside and outside measurements.

Protect sensitive electronics from damage while you take accurate measurements.

Switch between decimal and fractional measuring increments.

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

Measure center-to-center distances with the pointed jaws on these calipers, which are designed to self-center in holes.

Make accurate marks at precise measurements—these calipers have carbide-tipped jaws that press into workpieces for measuring and marking.

Quickly check that parts are within tolerance without resetting the caliper each time.

A low measuring force allows these calipers to accurately measure elastic and springy materials, such as plastic and rubber.

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