Accuracy before coverage
ThreadSizeGuide does not invent dimensions, standards values, shop tests or professional experience. Missing data remains unavailable. Conflicting sources remain visible until resolved.
Source priority
Official publications and legally accessible standards information come first, followed by manufacturer technical documentation and reputable specialist references. Community material can identify a question but does not independently support a critical value.
Human review boundary
Automated tests validate schema, formulas, routes, metadata and links. They do not replace technical judgment. New articles are excluded from public indexing until their evidence and exact revision have been reviewed.
Corrections
Corrections update the record, its review date and, when necessary, the calculation test case. Material revisions change the page’s updated date; silent changes to technical values are not acceptable.
