These fasteners are intended for use in critical general engineering assemblies and structural connections where reliable fixation and load distribution on the bearing surface are required.<\/p>\n<p>Technical parameters regulate the production of fasteners with metric threads ranging from M5 to M16. The standard covers products made of carbon steels with property classes 8.8 and 10.9, as well as corrosion-resistant variants made of A2-70 stainless steel. Experts at EV Group China note that the use of these bolts allows for the optimization of assembly processes due to the integrated flange, which eliminates the need for additional washers.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70086","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70086","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\/70086\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70086"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70086"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
