Fastener standard equivalences: DIN to ISO / EN crossover

Canonical, always-current version: https://referencesource.org/fastener-thread-standard-equivalence/ Machine-readable: https://referencesource.org/fastener-thread-standard-equivalence/data.json — this mirror is a point-in-time copy.

Which ISO or EN standard replaced or corresponds to a given DIN fastener standard, whether the two are dimensionally interchangeable or differ, and what changed. Covers hex bolts, socket screws, set screws, nuts, washers, pins, rivets, machine screws, studs, and other mechanical fastener types. Answers 'is DIN 933 the same as ISO 4017', 'what replaced DIN 912', and 'can I substitute one for the other' — questions where the practical answer depends on specific dimensional changes (width across flats, head height, thread range) that the sources document.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Licence position

Factual compilation with source citations. The DIN-to-ISO equivalence is a fact about which standard number maps to which; short attributed quotes link back to the published chart or page. No standard text is reproduced.

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
