  • Tension bolt having adjustable stress level
    Patent number: 4981404
    Abstract: For anchoring heavy machinery to foundations, previously tensioned stress-level indicating bolt connectors are provided. In a top axial cavity of the connector, threads are provided to mount an angularly adjustable stress-level indicating pin. In use, when the design tension stress level is reached and the connector thereby extended, angular freedom or restraint of the gaging pin indicates that the pre-set stress has been reached or exceeded. Indicia angularly arranged on the connector end facilitate adjustment of the pin to provide upper or lower stress levels.
