Abstract
A rotatably engaging head for a fastener for attaching a complementary panel member to a support member. The head includes a substantially flat underside and also includes a generally radially extending slit. One edge of the slit is connected to and defined by a lead-in tongue spaced above and generally parallel to the head. The tongue permits facile introduction of the head through an aperture in the panel, which aperture is smaller than the head. Extending from the head is a shank, for engagement of the support member to the panel member.
Claims5
In a resilient fastener for attaching a complementary panel member to a support member, said panel member and said support member each including an aperture, said fastener comprising:
- a head of larger diameter than said panel member aperture, said head including an upperside, an underside and a circumferential edge;
- a shank extending from said underside of said head;
- said head having a slit extending radially inwardly from said circumferential edge of said head;
- and a lead-in tongue spaced above and generally parallel to said upperside of said head, said lead-in tongue being connected to said upperside of said head along one side of said slit for the introduction of said head into and through said panel member aperture as said fastener is rotated relative to said panel member aperture, said lead-in tongue circumferentially overlapping and substantially covering said slit for its entire length and overlapping a portion of said upperside of said head.
