A carton may say \u201cM16 bolts,\u201d but without grade, material, finish, and batch information, receiving teams cannot confirm whether the goods match the purchase order.<\/p>\n\n\n\n<p>For industrial buyers, wrong-spec delivery is not only a paperwork issue. It can lead to assembly failure, customer claims, project delays, or costly sorting work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Grade Labeling Matters<\/h2>\n\n\n\n<p>Fastener grade defines mechanical performance. A class 8.8 bolt is not the same as class 10.9. A2-70 stainless steel is not the same as A4-80. ASTM A193 B7 stud bolts should not be mixed with general carbon steel rods.<\/p>\n\n\n\n<p>Buyers sourcing <a href=\"https:\/\/xzfastener.com\/ru\/products-category\/high-strength-fasteners\/\">high-strength fasteners<\/a> should treat grade labeling as part of quality control, not only packaging.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Should Be on a Fastener Label?<\/h2>\n\n\n\n<p>A clear label should allow warehouse staff to identify the product without opening every carton.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Label Item<\/th><th>Example<\/th><th>Why It Matters<\/th><\/tr><\/thead><tbody><tr><td>Product name<\/td><td>Hex bolt, nut, washer, threaded rod<\/td><td>Identifies the part type<\/td><\/tr><tr><td>\u0421\u0442\u0430\u043d\u0434\u0430\u0440\u0442<\/td><td>DIN 933, ISO 4017, ASTM A193<\/td><td>Confirms dimensional requirement<\/td><\/tr><tr><td>Size<\/td><td>M16 \u00d7 80, 1\/2\u201d-13 \u00d7 2\u201d<\/td><td>Prevents mixed-size delivery<\/td><\/tr><tr><td>Grade \/ class<\/td><td>8.8, 10.9, A2-70, B7<\/td><td>Confirms strength requirement<\/td><\/tr><tr><td>\u041c\u0430\u0442\u0435\u0440\u0438\u0430\u043b<\/td><td>Carbon steel, 304, 316, alloy steel<\/td><td>Avoids material confusion<\/td><\/tr><tr><td>Finish<\/td><td>Zinc plated, HDG, black oxide<\/td><td>Confirms surface treatment<\/td><\/tr><tr><td>Quantity<\/td><td>500 pcs, 25 kg, 100 sets<\/td><td>Supports receiving accuracy<\/td><\/tr><tr><td>Batch number<\/td><td>Lot No. or heat No.<\/td><td>Supports traceability<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>For full product planning, buyers can review <a href=\"https:\/\/xzfastener.com\/ru\/home\/products\/\">fastener products<\/a> before setting labeling rules.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Grade Labeling Mistakes<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Mixing Grade Systems<\/h3>\n\n\n\n<p>Metric property classes and inch-grade systems should not be mixed casually.<\/p>\n\n\n\n<p>For example, metric class 10.9 and SAE Grade 8 are not the same label system, even if both are high-strength categories. The PO, carton label, packing list, and inspection report should use the same system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Missing Stainless Steel Grades<\/h3>\n\n\n\n<p>For stainless steel orders, labels should clearly show 304, 316, A2-70, A4-70, or A4-80 where applicable. This is especially important for <a href=\"https:\/\/xzfastener.com\/ru\/fastener-material\/stainless-steel\/\">stainless steel fasteners<\/a> used in outdoor, marine, or chemical applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vague Surface Finish Terms<\/h3>\n\n\n\n<p>\u201cGalvanized\u201d may mean zinc plated or hot-dip galvanized. These are different finishes. For corrosion-sensitive orders, compare <a href=\"https:\/\/xzfastener.com\/ru\/products-category\/various-coated-fasteners\/\">coated fasteners<\/a> and require exact finish wording on labels.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Buyer\u2019s Labeling Checklist<\/h2>\n\n\n\n<p>Before shipment, confirm:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Carton labels match the PO.<\/li>\n\n\n\n<li>Grade appears clearly on each carton.<\/li>\n\n\n\n<li>Batch number matches the inspection report.<\/li>\n\n\n\n<li>Mixed-size orders have separate labels.<\/li>\n\n\n\n<li>Labels match the packing list and invoice.<\/li>\n\n\n\n<li>Custom parts show drawing or item number.<\/li>\n\n\n\n<li>Private label requirements are approved before packing.<\/li>\n<\/ol>\n\n\n\n<p>For drawing-based items, use <a href=\"https:\/\/xzfastener.com\/ru\/products-category\/custom-non-standard-fasteners\/\">custom non-standard fasteners<\/a> and include the drawing revision on the label.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Final Advice<\/h2>\n\n\n\n<p>Fastener grade labeling prevents wrong-spec delivery before it becomes a warehouse or field problem.
