ABSTRACT:
A fastener with a metal stud removably receivable in a plastic carrier member. A shank of the stud is inserted through a hole in the carrier member and an enlargement on the shank limits the extent to which the shank can be pushed through the hole. The stud is retained in the carrier member by entrapment of a portion of the carrier member surrounding the hole between the enlargement and a ring on the shank which has an interference fit with the hole. To facilitate inserting the ring into and removing it from the hole, the sides of the ring are tapered. The carrier member can be journaled on the shank to rotate freely with respect to the stud. If it is desired to prevent this rotation, the enlargement can have a non-circular configuration and be received in a mating non-circular recess in the carrier member.
