It may control dimensions, thread length, tolerance, head geometry, mechanical properties, and sometimes testing references.<\/p>\n\n\n\n<p>A strong RFQ should not only say \u201chex bolt\u201d or \u201cwasher.\u201d It should identify the standard, size, grade, finish, quantity, and certificate requirement.<\/p>\n\n\n\n<p>For common metric items, buyers can start with standard product categories such as <a href=\"https:\/\/xzfastener.com\/fr\/products-category\/standard-fasteners\/\">attaches standards<\/a>, then confirm details against drawings or project specifications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Cross Reference Examples<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Reference Table for Buyers<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Type de produit<\/th><th>Older \/ Common Reference<\/th><th>Common ISO or Market Reference<\/th><th>Attention de l'acheteur<\/th><\/tr><\/thead><tbody><tr><td>Boulon hexagonal \u00e0 filetage complet<\/td><td>DIN 933<\/td><td>ISO 4017<\/td><td>Check head size and thread length rules<\/td><\/tr><tr><td>Boulon hexagonal \u00e0 filetage partiel<\/td><td>DIN 931<\/td><td>ISO 4014<\/td><td>Do not assume same shank length<\/td><\/tr><tr><td>\u00c9crou hexagonal<\/td><td>DIN 934<\/td><td>ISO 4032<\/td><td>Confirm nut height and grade<\/td><\/tr><tr><td>Rondelle plate<\/td><td>DIN 125<\/td><td>ISO 7089 \/ ISO 7090<\/td><td>OD and thickness may differ<\/td><\/tr><tr><td>Vis \u00e0 t\u00eate creuse<\/td><td>DIN 912<\/td><td>ISO 4762<\/td><td>Check drive size and head dimensions<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>For a deeper metric standards review, the <a href=\"https:\/\/xzfastener.com\/fr\/din-iso-fastener-standards-complete-overview-for-industrial-buyers\/\">Guide des normes de fixation DIN et ISO<\/a> is a useful internal reference before sending RFQs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Most Common RFQ Mistakes<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Cross Reference Does Not Mean Full Replacement<\/h3>\n\n\n\n<p>A cross reference is a guide.
