ABSTRACT:
A method of fastening and a fastening assembly are disclosed, where a nut may be retained in a grooved channel by a resilient retainer. The retainer has a central portion with an opening in registry with the threaded opening of the nut and also has two wings extending in opposite directions outward from the central portion. The wings have sharp edges to grip into the channel. A tool with projections is used to disengage the wings from the channel and permit the assembly to be slid along the grooved channel to a desired position. Upon withdrawal of the tool, the sharp edges of the wings resiliently grip into the channel to releasably retain the nut in the channel.
