Vague notes such as \u201csteel\u201d or \u201cstainless\u201d are not enough for production.<\/p>\n\n\n\n<p>Check whether the drawing specifies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon steel, alloy steel, stainless steel, brass, aluminum, or special alloy<\/li>\n\n\n\n<li>Klasse oder Eigenschaftsklasse<\/li>\n\n\n\n<li>W\u00e4rmebehandlung<\/li>\n\n\n\n<li>H\u00e4rtebereich<\/li>\n\n\n\n<li>Tensile or proof load requirement<\/li>\n\n\n\n<li>Zertifikatspflicht<\/li>\n<\/ul>\n\n\n\n<p>If the fastener is used for load-bearing work, the inspection report should confirm that the final part matches the required grade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Review Surface Finish and Coating<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Coating Can Change Fit<\/h3>\n\n\n\n<p>Coating is not only appearance.
