Abstract: A fastener assembly includes an insert having a head and a sleeve extending from a bottom surface of the head, with the insert further defining an internal cavity. The head of the insert abuts a first panel with the sleeve extending through a first preformed hole in the first panel. A second panel with a second preformed hole is aligned with the first panel, and a shaft of a fastener pin is inserted through the second preformed hole and into the internal cavity of the insert. Upon rotating the fastener pin, a tee portion at the end of the shaft engages a seat positioned in the internal cavity of the insert. The fastener assembly also includes a compression member positioned around the shaft of the fastener pin that biases the tee portion of the fastener pin into engagement with the seat of the insert.
