A molded plastic, push-on fastener for connection to threaded studs or the like comprises first and second cylindrical collar members. The first collar has a resilient side wall and threads are formed on the interior thereof in a form and size for positive engagement with the threads on the associated threaded stud. The second collar member has a relatively rigid side wall with an open interior diameter which is greater than the diameter of the first collar member to permit the second member to be received over and surround the first member. A thin frangible, connecting web is provided for temporarily connecting the collar members in axial alignment. Cooperating interengaging thread forms are formed on the exterior of the first collar member and the interior of the second collar member. These interengaging thread forms act to inhibit radial expansion of the first collar member while simultaneously preventing axial withdrawal of the second member in a direction off the first member after the second member has been moved from the temporarily connected position to an installed position received over and surrounding the first collar member.
