If you only need (not the full standard), many engineering handbooks and fastener supplier websites (e.g., Würth, Bossard, McMaster-Carr) publish the key tables for free and legally. Summary “DIN 933 PDFCOFFEE” is a search for a free, likely pirated copy of the German hexagon full-thread bolt standard on a document-sharing site.
