Use these gauges to check the outside diameter of shafts, rods, and other cylindrical objects to determine whether they’re in tolerance.
Set inside micrometers, dial bore gauges, and other precision tools.
Often used with go and no-go ring gauges, these holders keep two ring gauges still for quick, repeat measuring.
Not only were these gauges calibrated in a lab, but they also come with a certificate that's traceable to NIST.
Check a part’s external threads to make sure they fall within tolerance. You can use these for bolts, threaded rods, bits, and more.
These gauges come with a certificate that’s traceable to NIST, confirming they were calibrated in a lab. Use them to verify whether external pipe threads are within tolerance.
Confirm that external pipe threads are sized within tolerance.
Join two ring gauges with different sizes to quickly check if threads are within tolerance. Secure your gauges to these holders with the included fasteners.
Test if the left-hand threads on parts fall within tolerance.
Calibrated in a lab and backed by a certificate traceable to NIST, these gauges check if left-hand threads fall within tolerance.
