    • A gage for measuring the external threads of a threaded body has a segment housing formed from a housing body. The housing body has a generally U-shaped cross section with a bottom extending between a pair of opposite, upright sidewalls so that a channel with a longitudinal axis is defined. First and second gage segments are configured to engage the threads of the threaded body when the threaded body is positioned between the first and second segments and the first and second segments are closed together. The first gage segment is fixed to the housing body, and the second gage segment is received within the channel of the housing body. The second gage segment moves linearly within the channel along the longitudinal axis to allow the first and second segments to be separated for insertion of the threaded body between the first and second segments. This also allows the first and second segments to be closed together for engagement with the threaded body. An indicator having a movable indicator shaft that actuates the indicator is mounted to the housing body. The indicator shaft is spring loaded so that the indicator shaft projects into the channel of the housing and engages the second gage segment, urging the second gage segment within the channel into engagement with the threaded body.
    • 用于测量螺纹体的外螺纹的量具具有由壳体形成的段壳体。 壳体具有大致U形的横截面,其底部延伸在一对相对的直立侧壁之间,从而限定了具有纵向轴线的通道。 当螺纹体定位在第一和第二段之间并且第一和第二段闭合在一起时,第一和第二量规段被构造成接合螺纹体的螺纹。 第一量规段固定到壳体上,第二量规段被容纳在壳体的通道内。 第二量规段沿着纵向轴线在通道内线性移动,以允许第一和第二段被分离以将螺纹体插入在第一和第二段之间。 这也允许第一和第二段被关闭在一起以与螺纹体接合。 具有致动指示器的可移动指示器轴的指示器安装到壳体。 指示轴是弹簧加载的,使得指示器轴突出到壳体的通道中并接合第二量规段,将通道内的第二量规段推向与螺纹体接合。
