Therefore, a small amount of rotation can produce a quick and large vertical movement.<\/p>\n<p>Generally, multi-joint screws are often used when threading a thin cylinder such as a fountain pen, because the larger travel distance per revolution of a single-joint screw in a cylinder causes the groove width to increase, which may result in insufficient strength.<\/p>\n","protected":false},"featured_media":23601,"template":"","commitments_category":[466],"class_list":["post-23600","commitments","type-commitments","status-publish","has-post-thumbnail","hentry","commitments_category-standards"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/commitments\/23600","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/commitments"}],"about":[{"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/types\/commitments"}],"version-history":[{"count":3,"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/commitments\/23600\/revisions"}],"predecessor-version":[{"id":24234,"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/commitments\/23600\/revisions\/24234"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/media\/23601"}],"wp:attachment":[{"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/media?parent=23600"}],"wp:term":[{"taxonomy":"commitments_category","embeddable":true,"href":"https:\/\/www.nakaya.org\/en\/wp-json\/wp\/v2\/commitments_category?post=23600"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
