Due to their increased thickness and outer diameter, these fasteners effectively distribute axial pressure on the bearing surface, preventing deformation of the connected parts.<\/p>\n<p>EV Group China engineers recommend using DIN 7349 washers in critical metal structures, mechanical engineering, and construction assemblies where high load-bearing capacity of the fastener connection and protection of holes against crushing are required. Using high-quality hardware from EV Group China guarantees a long service life for the assembly, even under vibration loads.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[116,122],"class_list":["post-66920","wiki","type-wiki","status-publish","hentry","wiki_category-din","wiki_category-standarty"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/66920","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\/66920\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=66920"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=66920"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
