ABSTRACT:
A fastener is provided having a bolt releasably securable to a nut. The bolt includes a collar and resilient locking prongs with shoulders to anchor the bolt to a first member, such as a grommet or panel, and the nut has a nut body and resilient locking prongs with shoulders to anchor the nut to a second body, such as a second grommet or panel. A bolt shank having several curved channels open at one end and having locking slots at the other end is insertable into a cavity in the nut which has engagement lugs disposed therein. Rotation of either the nut or the bolt causes the engagement lugs to travel within the channels and engage the locking slots, thereby securing the nut to the bolt. Either a spring washer or resilient collar material can be used to apply a locking force to urge the nut and bolt in opposite directions to ensure that the lugs remain in the locking slots. Pressing the lug and nut together with an unlocking force greater than the locking force allows the nut and bolt to disengage.
