    Introduction to GB\/T 5779.1-2000 Standard The GB\/T 5779.1-2000 standard specifies general requirements for surface defects on fasteners, particularly bolts, screws, and studs. This standard is essential for ensuring the quality and reliability of mechanical fasteners in various industries, including automotive, aerospace, construction, and machinery manufacturing. It defines acceptable limits for surface imperfections that could compromise structural integrity, performance, or safety. By adhering to this standard, manufacturers can maintain consistency in production, while users benefit from predictable fastener behavior under load. Surface defects in fasteners arise from manufacturing processes such as forging, heat treatment, and machining. These defects, if not controlled, can lead to premature failure through mechanisms like stress concentration […]<\/p>","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[220],"tags":[],"class_list":["post-5642","post","type-post","status-publish","format-standard","hentry","category-technical-documentation-and-references"],"_links":{"self":[{"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts\/5642","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/comments?post=5642"}],"version-history":[{"count":2,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts\/5642\/revisions"}],"predecessor-version":[{"id":5644,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts\/5642\/revisions\/5644"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/media?parent=5642"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/categories?post=5642"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/tags?post=5642"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
