Abstract
A fastener for attaching together layers of a substrate. The fastener includes a slide body, a bolt, a conical spring, and a toggle having a pivot coupled with one end of the slide body. The conical spring is disposed over a shaft of the bolt and the shaft is engaged within the slide body. The slide body and toggle are inserted into an aperture through the layers of substrate in a first configuration until the conical spring contacts a front face of the layers of substrate. Compression of the conical spring against the front face advances the toggle a clearance length out of the aperture on a back face of the layers of a substrate such that the toggle can switch to a second configuration that prevents retraction through the aperture. Extension of the conical spring automatically engages the toggle with the back face of the substrate to prevent rotation of the slide body within the aperture.
