Check that holes tapped for helical threads are within tolerance. To speed up tests, these gauges have a go gauge on one end and a no-go gauge on the other.

Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly.

Test thread tolerance in seconds. A time-saver for high-volume work, these drivers quickly thread gauges in and out of holes for you—just pull the trigger.

Check the true diameter of holes, even if they’re bent or curved. The thin stem on these gauges flexes to reach features deep inside holes and cavities.
