Effective date: Apr 2026  |  Last updated: Apr 2026  |  Version: 1.0

READ BEFORE USE: ThreadChaser is a reference and identification aid only. Results must always be independently verified with calibrated, traceable measurement instruments before any engineering, manufacturing, maintenance, or safety-critical application. Do not rely solely on this website for decisions where incorrect thread identification could cause injury, death, or property damage.

1. General Disclaimer

The information, calculations, and thread identification results provided by threadchaser.com (the "Website") are furnished by ThreadChaser ("Developer") on an "as is" and "as available" basis, for general informational and reference purposes only.

Nothing on the Website constitutes professional engineering advice, certified metrology output, a formal conformance assessment, or a warranty of fitness for any specific application or purpose. The Developer makes no representations or warranties, express or implied, as to the accuracy, reliability, completeness, or suitability of any information or result produced by the Website.

2. No Engineering or Professional Advice

ThreadChaser is not a substitute for qualified engineering judgment. Thread identification and selection for any structural, mechanical, pressure-containment, safety-critical, or load-bearing application must be carried out or reviewed by a suitably qualified engineer or technician using certified instruments and applicable technical standards.

The Developer is not a registered engineering firm and no content on the Website should be interpreted as constituting engineering advice or opinion.

3. Measurement Accuracy and Database Limitations

Thread matching results are computed by comparing user-entered dimensions against a reference database of nominal thread values. The accuracy of any result is therefore subject to:

Always verify: A "match" indicated by ThreadChaser means only that your entered measurements fall within the configured tolerance percentage of a nominal standard value. It is not a certificate of conformance, and the matched standard may not be the correct one for your application.

4. Limitation of Liability

To the maximum extent permitted by applicable law, the Developer expressly excludes all liability for any loss or damage of any kind — including but not limited to:

arising directly or indirectly from:

This limitation of liability applies regardless of the form of action — whether in contract, tort (including negligence), strict liability, or otherwise — and even if the Developer has been advised of the possibility of such damages.

In jurisdictions that do not permit the complete exclusion of liability, the Developer's total liability shall be limited to the fullest extent permitted by law and in no event shall exceed AU$1.00.

5. Third-Party Standards and Intellectual Property

The thread standards referenced on the Website (including ISO, ASME, BS, ANSI, ASA, DIN, and others) are the intellectual property of their respective issuing bodies. ThreadChaser references publicly available nominal dimensional data from these standards for informational purposes. The Developer is not affiliated with, endorsed by, or acting on behalf of any standards organisation.

Users requiring definitive or legally compliant dimensional data should obtain and consult the current published edition of the relevant standard directly from the issuing body (e.g. ISO, ASME, BSI, ANSI, DIN).
