Introduction GB\/T 3098.4 is a Chinese national standard that specifies the mechanical properties of fine pitch thread nuts for fasteners. This standard covers marking systems, materials, and mechanical performance requirements for nuts with fine threads, ensuring compatibility with bolts, screws, and studs. It applies to nuts with nominal heights and effective thread lengths as defined, focusing on performance grades to guarantee reliability in mechanical assemblies. The standard emphasizes preventing thread stripping failures by prioritizing bolt fracture in over-torquing scenarios, enhancing safety in applications. Marking System The marking system in GB\/T 3098.4 distinguishes nuts based on their nominal height and effective thread length. 3.1 Nuts with Nominal Height \u2265 0.8D (Effective […]<\/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-5569","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\/5569","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=5569"}],"version-history":[{"count":1,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts\/5569\/revisions"}],"predecessor-version":[{"id":5571,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/posts\/5569\/revisions\/5571"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/media?parent=5569"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/categories?post=5569"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/ja\/wp-json\/wp\/v2\/tags?post=5569"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
