Threaded Plug Gauges for Internal Threads

Go/No-Go Threaded Plug Gauges with Handle

Speed up thread tolerance checks—the handle on these gauges gives you a good grip to quickly thread and unthread go or no-go gauges.

Go/No-Go Helical Insert Threaded
Plug Gauges with Handle

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.

Go/No-Go Left-Hand Threaded
Plug Gauges with Handle

A go and no-go gauge in one, these gauges check that left-hand threads fall within tolerance.

Threaded Plug Gauges with
Handle for Pipe Threads

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.

Threaded Plug Gauges

Test if internal threads fall within tolerance.

Threaded Ring Gauges for External Threads

Threaded Ring Gauges with Calibration Certificate

Not only were these gauges calibrated in a lab, but they also come with a certificate that's traceable to NIST.

Threaded Ring Gauges

Check a part’s external threads to make sure they fall within tolerance. You can use these for bolts, threaded rods, bits, and more.

Threaded Ring Gauges for Pipe
Threads with Calibration Certificate

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.

Left-Hand Threaded Ring Gauges
with Calibration Certificate

Calibrated in a lab and backed by a certificate traceable to NIST, these gauges check if left-hand threads fall within tolerance.

Left-Hand Threaded Ring Gauges

Test if the left-hand threads on parts fall within tolerance.

Outside Micrometers for Screw Threads with Calibration Certificate

Outside Micrometers for Screw
Threads with Calibration Certificate

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