Outline
 
 
    Limit Gage for Screw is set as the same grade as standards of screws
       and tested by 2 limit methods as passing side and stop side.  
    The screw is passed if pass side gage passes
       through without difficulty and stop side gage stops within 2 turns.
    Manages by checking passing or stopping limit of screw.
     Meter Screw Gage is broadly divided into
      ISO Grade Gage and 1.2.3 Grade Gage.
