Abstract
A fastening device for connection to threaded bolts or studs. The device is preferably molded from plastic and has an internal opening provided with one or more resilient catch projections distributed about the circumference of the opening. The projections extend axially and radially into the opening. A series of graduations or thread-form configurations are carried by each projection. When a bolt is received in the opening, the projections are resiliently deflected and the graduations engage the threads of the bolt.
