Thread Plug Gages Instrument Information

Thread plugs play a crucial role in ensuring accurate thread fit for quality control in various industries. Fox Valley Metrology provides ISO/IEC 17025 accredited calibration services for thread plugs, delivering high precision and full NIST traceability for reliable measurements in every application.

Our expert technicians utilize advanced equipment to ensure accuracy across the full range of thread plug types. For in-lab calibration, we are capable of measurements up to 40 inches, while on-site services are performed up to eight inches.

We employ the most thorough processes available to ensure proper fit and the utmost level of tolerance compliance. Both “go” and “no-go” thread plug members are calibrated through our standard thread plug calibration process:

Multi-Point Inspection: We inspect the front, middle, and back of the “go” side, as well as the front and back of the “no-go” side, confirming accuracy throughout the entire gage length.
Pitch Diameter Verification: Using the precise 3-wire method, we verify the pitch diameter to ensure threading accuracy.

Fox Valley Metrology’s ISO/IEC 17025 Accredited Thread Plug Gage Calibration Services Include:

Taperlock Thread Plug Calibration
Reversible Thread Plug Calibration
Trilock Thread Plug Calibration

With our comprehensive and precise calibration process, you can rely on your thread plug gages for dependable thread accuracy, supporting your quality control needs across all applications.”

What is a Thread Plug?

A metallic cylinder, containing a handle, machined to a precise diameter and threaded to a precise size. The gage is screwed into the internal thread of a machined part. The gage often comes in a Go/No-Go combination, connected by a handle. Often, the machined part is considered in tolerance if the Go end goes into the threaded hole smoothly and the No-Go end engages, but does not thread over three complete turns.

Common Thread Plug Uses

Verifying that internal threads on machined parts meet specified dimensions and tolerances for proper mating with external threaded parts.

Common Thread Plug Classes

UN Series Thread Plugs:
• UNC – Coarse pitch series
• UNF – Fine pitch series
• UNEF – Extra fine pitch series
• UNJ – Constant pitch series, with rounded root on external threads & thread ring gage
• UNJC – Coarse pitch series, rounded root on external threads & thread ring gage
• UNS – Special diameter, pitch or length of engagement
• UNJF – Fine pitch series, rounded root on external threads & thread ring gage
• UNJEF – Extra fine pitch series, rounded root on external threads & thread ring gage

Metric Thread Plugs:
•M – Basic thread profile as specified in ISO 68
•MJ – MJ profile with round root on external threads and thread ring gage
•MJS – MJ profile special series on external threads and thread ring gage

Why is thread plug gage calibration necessary?

Thread plug gage calibration verifies the accuracy of a plug gage by comparing its readings to an established thread plug gauge standard. Wear and tear, environmental conditions and other factors impact the calibration of thread plug gages.

How often is thread plug gage calibration needed?

The frequency of thread plug gage calibration depends on how much the gage is used and in what environments. It is often recommended as little as once per year or every few months, depending on the circumstances.

Why is thread plug gage calibration important?

Thread plug gage calibration is key to ensuring thread plugs are accurate. In doing so, you can ensure the components the thread plug is inspecting will have connections that fit snugly and properly.

What is the process for calibrating a thread plug gage?

Calibration of a thread plug includes inspection of the front, middle and back of both the go and no-go members. This is done using a universal length measuring (ULM) machine. The pitch diameter can then be inspected by using the 3-wire method.

How long does thread plug calibration take?

Expect an average 3-5 day turnaround for our caliper calibration service, with faster options offered if needed.

What is the cost of thread plug calibration?

Costs depend on the size of the thread plug as well as its series (UN, Metric, BSPP, etc.). To ensure accurate pricing, please reach out for a quote today.

Can I calibrate thread plug gages in-house?

In-house calibration is possible with the right tools and expertise, but professional services are recommended to ensure accuracy and traceability back to national standards.

How do I know if my thread plug needs calibration?

If you can see visible wear on the threads, calibration is necessary. Additionally, if the thread plug is dropped, it should be calibrated (even if damage is not visible).

Yes. We provide ISO 17025 accredited thread plug calibrations on all calibrations.

Is your thread plug calibration traceable to national standards?

Yes. We NIST traceable thread ring calibrations on all calibrations.
