Abstract
The fastener includes a post element, a blind aperture assembly with a blind aperture into which the post element is inserted, and a rigid fastening member. The rigid fastening member includes a lower helical edge with an inwardly extending lip which threadably engages the external threads formed on the post. The inclined rotationally symmetric wall deflects upon insertion into the blind aperture, but then interferes with the walls of the blind aperture to resist withdrawal.
