It affects whether bolts, nuts, washers, and complete bolting assemblies can be accepted on European construction projects.<\/p>\n\n\n\n<p>Many problems start with a simple misunderstanding. A buyer asks for \u201cM20 grade 8.8 structural bolts.\u201d The supplier quotes standard bolts. Later, the project asks for CE-marked EN 15048 or EN 14399 assemblies, Declaration of Performance, marking, and traceability.<\/p>\n\n\n\n<p>At that point, price and delivery schedule may both change.<\/p>\n\n\n\n<p>For project buyers, CE compliance should be confirmed before quotation, not before shipment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What CE Compliance Means for Structural Fasteners<\/h2>\n\n\n\n<p>CE marking shows that a construction product has declared performance under the applicable European system. For structural fasteners, this usually means the product must follow the relevant harmonized EN standard and be supported by required documents.<\/p>\n\n\n\n<p>It is not a general quality logo. It is tied to product performance, factory control, marking, and documentation.<\/p>\n\n\n\n<p>For structural bolting projects, buyers should confirm:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Applicable EN standard<\/li>\n\n\n\n<li>CE marking requirement<\/li>\n\n\n\n<li>Declaration of Performance<\/li>\n\n\n\n<li>Manufacturer identification<\/li>\n\n\n\n<li>Product or assembly marking<\/li>\n\n\n\n<li>Batch traceability<\/li>\n\n\n\n<li>Inspection documents<\/li>\n\n\n\n<li>Packaging label requirements<\/li>\n<\/ul>\n\n\n\n<p>Buyers sourcing <a href=\"https:\/\/xzfastener.com\/ar\/products-category\/high-strength-fasteners\/\">high-strength fasteners<\/a> should treat these requirements as part of the product specification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">EN 15048 vs EN 14399<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Confirm the Connection Type First<\/h3>\n\n\n\n<p>The first question is whether the connection is non-preloaded or preloaded. The project design should answer this.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>\u0642\u064a\u0627\u0633\u064a<\/th><th>Fastener Type<\/th><th>Typical Use<\/th><th>Buyer Focus<\/th><\/tr><\/thead><tbody><tr><td>EN 15048<\/td><td>Non-preloaded structural bolting assemblies<\/td><td>Structural joints without controlled preload<\/td><td>SB assembly, marking, DoP, traceability<\/td><\/tr><tr><td>EN 14399<\/td><td>High-strength structural bolting assemblies for preloading<\/td><td>Preloaded structural connections<\/td><td>HV\/HR system, washer matching, preload control<\/td><\/tr><tr><td>EN 1090 project execution<\/td><td>Steel and aluminum structure execution<\/td><td>Installation and inspection control<\/td><td>Tightening method, site acceptance<\/td><\/tr><tr><td>Project specification<\/td><td>Job-specific requirement<\/td><td>Bridges, buildings, towers, plants<\/td><td>Final approval rules<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Do not replace EN 14399 with EN 15048 unless the project engineer approves it.

Complete Assembly Requirement<\/h3>\n\n\n\n<p>Structural fasteners are often checked as assemblies. A bolt alone may not be enough. The nut and washer must match the system.<\/p>\n\n\n\n<p>Confirm:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bolt type and standard<\/li>\n\n\n\n<li>Nut grade and standard<\/li>\n\n\n\n<li>Washer type, hardness, and coating<\/li>\n\n\n\n<li>Assembly marking<\/li>\n\n\n\n<li>Lot number<\/li>\n\n\n\n<li>Manufacturer mark<\/li>\n\n\n\n<li>Original packaging condition<\/li>\n<\/ul>\n\n\n\n<p>For full product planning, buyers can review the complete <a href=\"https:\/\/xzfastener.com\/ar\/home\/products\/\">fastener products<\/a> range.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Marking and Packaging<\/h3>\n\n\n\n<p>Marking matters during site inspection. If the carton label, product marking, and document batch number do not match, the goods may be delayed or rejected.<\/p>\n\n\n\n<p>Check the packaging for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CE-related label information<\/li>\n\n\n\n<li>Standard reference<\/li>\n\n\n\n<li>Assembly type<\/li>\n\n\n\n<li>Size and grade<\/li>\n\n\n\n<li>\u0643\u0645\u064a\u0629<\/li>\n\n\n\n<li>Batch number<\/li>\n\n\n\n<li>Manufacturer identification<\/li>\n\n\n\n<li>Coating or finish description<\/li>\n<\/ul>\n\n\n\n<p>Do not open and repack structural assemblies casually. Repacking can create traceability problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Declaration of Performance<\/h3>\n\n\n\n<p>The Declaration of Performance should match the product, standard, manufacturer, and intended use. It should not be treated as a generic certificate.<\/p>\n\n\n\n<p>Before shipment, confirm that the DoP matches:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>EN 15048 or EN 14399 requirement<\/li>\n\n\n\n<li>Product type<\/li>\n\n\n\n<li>Size range<\/li>\n\n\n\n<li>Performance characteristics<\/li>\n\n\n\n<li>Manufacturer information<\/li>\n\n\n\n<li>CE marking details<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Coating and Corrosion Protection<\/h2>\n\n\n\n<p>Surface finish can affect both compliance and installation. Structural fasteners may be supplied plain, zinc plated, hot-dip galvanized, zinc flake coated, or with another approved system.<\/p>\n\n\n\n<p>Coating affects:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Corrosion resistance<\/li>\n\n\n\n<li>Thread fit<\/li>\n\n\n\n<li>Nut running behavior<\/li>\n\n\n\n<li>Torque or preload control<\/li>\n\n\n\n<li>Packaging protection<\/li>\n\n\n\n<li>Inspection requirements<\/li>\n<\/ul>\n\n\n\n<p>For outdoor or corrosion-sensitive projects, compare <a href=\"https:\/\/xzfastener.com\/ar\/products-category\/various-coated-fasteners\/\">various coated fasteners<\/a> before finalizing the finish.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Buyer Mistakes<\/h2>\n\n\n\n<p>Avoid these issues:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Asking only for \u201cstructural bolts\u201d without EN standard.<\/li>\n\n\n\n<li>Ordering by grade only, such as 8.8 or 10.9.<\/li>\n\n\n\n<li>Mixing bolts and nuts from different sources.<\/li>\n\n\n\n<li>Requesting CE documents after production is finished.<\/li>\n\n\n\n<li>Ignoring original packaging and label rules.<\/li>\n\n\n\n<li>Confusing non-preloaded and preloaded assemblies.<\/li>\n\n\n\n<li>Approving coating without checking thread fit.<\/li>\n\n\n\n<li>Using standard stock bolts for CE-required structural projects.<\/li>\n<\/ul>\n\n\n\n<p>For special dimensions, coating zones, or drawing-based assemblies, use <a href=\"https:\/\/xzfastener.com\/ar\/products-category\/custom-non-standard-fasteners\/\">custom non-standard fasteners<\/a> and confirm CE-related requirements before production.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">RFQ Checklist for CE Structural Fasteners<\/h2>\n\n\n\n<p>A clear RFQ should include:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>RFQ Item<\/th><th>What to Specify<\/th><\/tr><\/thead><tbody><tr><td>Project standard<\/td><td>EN 15048, EN 14399, EN 1090, or project spec<\/td><\/tr><tr><td>Connection type<\/td><td>Non-preloaded or preloaded<\/td><\/tr><tr><td>Product assembly<\/td><td>Bolt, nut, washer details<\/td><\/tr><tr><td>Size<\/td><td>Diameter, length, thread pitch, thread length<\/td><\/tr><tr><td>\u062f\u0631\u062c\u0629<\/td><td>Property class or project grade<\/td><\/tr><tr><td>Coating<\/td><td>Plain, HDG, zinc flake, zinc plated, or specified finish<\/td><\/tr><tr><td>Documents<\/td><td>DoP, MTC, inspection report, coating report<\/td><\/tr><tr><td>Marking<\/td><td>CE-related marking, manufacturer mark, batch number<\/td><\/tr><tr><td>Packaging<\/td><td>Original labels, lot separation, carton marks<\/td><\/tr><tr><td>Inspection<\/td><td>Pre-shipment check and site acceptance requirements<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>If washers are part of the assembly, review <a href=\"https:\/\/xzfastener.com\/ar\/fastener-type\/washers\/\">washer products<\/a> and confirm hardness, dimensions, and coating compatibility.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Advice<\/h2>\n\n\n\n<p>CE compliance for structural fasteners should be checked at the RFQ stage.
