The standard applies to fasteners with metric threads in the diameter range from M3 to M20 inclusive. Products supplied by EV Group China comply with accuracy class A and are produced in strength classes 8.8, 10.9, and 12.9, which ensures the reliability of critical threaded connections in mechanical engineering and construction structures.<\/p>\n<h3>Engineering recommendations for operation<\/h3>\n<p>When designing assemblies using these fasteners, experts at EV Group China recommend considering the following key parameters:<\/p>\n<ul>\n<li>Strict adherence to the tightening torque limits specified in the notes to Tables 2 and 3 of this standard to avoid deformation of the countersunk head.<\/li>\n<li>Compliance of mating elements with international standards ISO 261 (threads), ISO 898-1 (mechanical properties of carbon and alloy steels), and ISO 965-2 (thread tolerances).<\/li>\n<li>If it is necessary to use fasteners with characteristics beyond standard versions, you should follow the regulations of ISO 4759-1.<\/li>\n<\/ul>\n<p>EV Group China provides expert quality control for each batch of fasteners, guaranteeing full compliance with the declared strength classes for operation under conditions of high static and dynamic loads.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[120],"class_list":["post-69785","wiki","type-wiki","status-publish","hentry","wiki_category-iso"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69785","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\/69785\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69785"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
