A fastener is provided to be pre-assembled to a substrate. The fastener comprises a shaft having a first end and a second end opposite the first end, and a thread portion adjacent to the second end; a head disposed on the first end; and a unidirectional retention member between the head and the thread portion. The unidirectional retention member is configured to pass through a mounting hole of the substrate in one direction such that the fastener is retained on the substrate once the unidirectional retention member has passed through the mounting hole.
