VÖLKEL Calibration service for thread plug gauges for cylindrical threads

• for the calibration of thread plug gauges for cylindrical internal threads
• for GO and NO GO inspection of dimensional conformity
• for inspection equipment monitoring, incoming goods inspection, production control and quality assurance
• for service workshops, maintenance, mechanical engineering and industrial thread inspection
• for documented evaluation of thread plug gauges in an inspection equipment management system

Note For cylindrical internal threads, inspection is carried out with thread plug gauges; the GO side must be usable without major resistance, while the NO GO side may only engage to a limited extent.

• factory calibration certificate directly from the manufacturer
• calibration in a measurement laboratory independent of manufacturing
• measurement on IAC thread scanners
• suitable for documented inspection equipment monitoring
• practical classification for thread plug gauges used in internal thread inspection

• The factory calibration certificate does not replace proper cleaning, protected storage and visual inspection of the thread plug gauge between calibration intervals.

1. Select the thread plug gauge for which a factory calibration certificate is required.
2. Check whether the thread plug gauge is intended for cylindrical internal threads.
3. Assign the test item to the relevant thread system and standard specification.
4. State the calibration request together with your order or inquiry.
5. The thread plug gauge is calibrated in the independent measurement laboratory on IAC thread scanners.
6. The results are documented in the factory calibration certificate.
7. File the certificate in your inspection equipment management system and assign it to the correct thread plug gauge.

What is the factory calibration certificate for thread plug gauges used for?
You use the factory calibration certificate to document the calibration of a thread plug gauge in a traceable way.

Which threads are checked with this thread plug gauge?
This thread plug gauge is used for cylindrical internal threads. The concrete assessment depends on the respective thread system and standard specification.

What does GO and NO GO mean in thread gauging?
The GO gauge verifies that the thread can be accepted from the functional side. The NO GO gauge checks the reject limit and may only engage within the specified limit.

Do I receive a factory calibration certificate with this service?
Yes. On request, we issue a factory calibration certificate as the manufacturer for the respective test item.

Which specifications are used to calibrate the thread plug gauge?
Calibration is carried out according to the specifications and standards defined for the respective test item, for example DIN, ISO or ANSI.

Why is calibration on IAC thread scanners relevant?
Calibration on IAC thread scanners supports precise and traceable inspection of thread gauges in industrial inspection equipment management.
