These products are characterized by a fine metric thread and belong to the category of precision fasteners of grade A. The standard regulates the production of hardware with a nominal thread diameter ranging from 8 to 16 mm inclusive.<\/p>\n<p>EV Group China supplies high-strength fasteners that meet strength classes 8.8, 10.9, 12.9, as well as corrosion-resistant designs made of A2-70 stainless steel. The use of precision fine threads allows for higher tightening forces with less torque, which is critical for demanding assemblies in mechanical engineering and metal structures.<\/p>\n<h3>Compliance with international standards<\/h3>\n<p>In cases where project documentation requires deviations from the basic EN 14219 specifications, EV Group China engineers recommend relying on harmonized standards that ensure component interchangeability and the reliability of threaded connections:<\/p>\n<ul>\n<li>ISO 724: Basic metric screw threads.<\/li>\n<li>ISO 888: Bolts, screws and studs &#8211; Nominal lengths, and thread lengths for general purpose bolts.<\/li>\n<li>EN ISO 898-1: Mechanical properties of fasteners made of carbon steel and alloy steel.<\/li>\n<li>ISO 965-2: General purpose metric screw threads &#8211; Tolerances.<\/li>\n<li>EN ISO 3506-1: Mechanical properties of corrosion-resistant stainless-steel fasteners.<\/li>\n<\/ul>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-69768","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69768","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69768\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69768"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69768"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
