ABSTRACT:
A one-piece plastic fastener is disclosed as being designed to be pushed on a threaded stud. The fastener has a head portion and a cylindrical body portion. The cylindrical body portion is formed with a pair of diametrically opposed rib sections extending the length of the body portion with the rib sections having equally spaced arcuate segments. In the interior of the cylindrical body portion a resilient wing member is integrally formed inwardly of the arcuate segment. A pair of longitudinally extending narrow ridges are formed on the interior of the cylindrical body with a thickness selected to cause the resilient wing members to be brought into threaded engagement with the threaded stud as the fastener is pushed onto the stud.
