  • Clearance indicator - blind measurement
    Patent number: 4241508
    Abstract: This invention is a machine component, specifically a bolt, incorporating a means of indicating the clearance the component has with an associated operating part. The device is in the form of a hollow bolt, within which is a slidable, but frictionally restrained, pin which protrudes from the head of the bolt. The device finds particular usefulness in mechanisms which, in the position in which the clearance is critical, are unaccessible for direct measurement.
