Abstract
A color pressure-sensitive fastener capable of providing a visual indication of a pressure threshold applied to the fastener is disclosed. The fastener includes a fastening portion which is actuated to fasten by way of application of a sufficient actuating pressure on an actuating surface of the fastening portion; and a pressure-sensitive substance associated with the actuating surface such that the actuating surface visibly changes color after the sufficient actuating pressure is applied to the actuating surface. This invention at least partially overcomes some of the disadvantages of typical fasteners, such as the lack of visual indication of proper installation of the fastener.
