          Introduction to Metric Thread Tolerances Metric screw threads, standardized under GB\/T 197 (equivalent to ISO 965), define tolerances for external and internal threads to ensure interchangeability and performance in mechanical assemblies. This guide focuses on external thread pitch diameter (d2) tolerances, which are critical for proper mating and load distribution. Tolerances account for manufacturing variations […]<\/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-5803","post","type-post","status-publish","format-standard","hentry","category-technical-documentation-and-references"],"_links":{"self":[{"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/posts\/5803","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/comments?post=5803"}],"version-history":[{"count":2,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/posts\/5803\/revisions"}],"predecessor-version":[{"id":5805,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/posts\/5803\/revisions\/5805"}],"wp:attachment":[{"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/media?parent=5803"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/categories?post=5803"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/korea-transmission.com\/zh\/wp-json\/wp\/v2\/tags?post=5803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
