  • Marine fastener system with interchangeable identification tags
    Patent number: 5394816
    Abstract: A marine fastener system in which interchangeable identification tags are secured to the fastener body by use of the very same screws which secure the fastener to the deck or mast. This avoids any need to make additional screw holes and yet permits a ready and permanent way of ascertaining the function of each fastener. It is possible to mark such tags using a luminous paint, so that the tags can easily be read in the dark.
