  • Patent number: 4590678
    Abstract: In order to check threads for accuracy, a single wire is placed in the notch formed by the thread flanks. The wire is sized to extend above the top of the thread crown or ridge. A micrometer is used to measure the distance between the exposed top of the wire on one side of the thread and the thread crown on the other side. This technique is an improvement over the conventional three wire system since far less manual dexterity is required.
