摘要: A plastic push-in or drive fastener having a enlarged head and shank is disclosed. The configured to allow the be pushed through complementary shaped aperture opening in an article using relatively low insertion force. helical screw rib formation on provides retention force opposing from being axially withdrawn while readily permitting withdrawal of response rotation about its axis. Moreover, prevent inadvertent separation which it passes.
