DIN · ISO · ASTM cross-reference
Gulf drawings mix German, international and American designations on the same sheet. This resolves them — and says where the "equivalent" is not actually identical, because that is where the mistakes hide.
Product standards
ISO replaced most DIN fastener standards. Dimensions are usually the same; the exceptions are listed in the last column and matter for spanners, access and templates.
Grade and property-class equivalents
"≈" means comparable duty, not interchangeable. Substitution across systems needs the project engineer's approval — the test methods and the acceptance limits differ.
