A molded, internally threaded fastening device adapted for receipt of a threaded member. The fastening device is molded in a generally flat position with two preferably joined complementary sections adapted to be manually folded over upon one another, in face-to-face relationship, to form the fastener. Each complementary section defines a generally concave cavity extending along the complementary face which will cooperate with the concave cavity in the complementary face of the other complementary section to define a generally axially extending threaded member receiving bore when the two complementary sections are folded over upon one another. Each concave cavity includes molded internal thread portions on the concave surface thereof which are adapted to cooperate and register with the molded thread portions in the other cavity to form a continuous internal thread along at least a part of the threaded member receiving bore. Each complementary section also includes at least one convexly extending loop which in connection with the concave cavity defines a substantially circular aperture. When the complementary sections are folded over upon one another, or are in the preassembled position, the apertures will form a portion of the threaded member receiving bore through which the threaded member must pass.
