Abstract
The tree fastener includes split wing fasteners which engage a passageway in a clip base, including flashgates in the passageway which were formed in the molding process initially joining the tree fastener and the clip base prior to driving to the pre-driven position, and further engage a structural aperture in the driven position. The tree fastener further includes a flexible tab which is joined to the tree fastener near the tip of the tree fastener and which extends upwardly within a slot in the shank of the tree fastener and extends through the head of the tree fastener. The flexible tab includes two generally radially outwardly extending interference bumps which engage one of the flashgates in the pre-driven position. The flexible tab can be manually moved radially inwardly so that the interference bumps release the flashgate so that the tree fastener can be urged to the fully driven position.
