    Abstract: A quick connect fastener wherein the receptacle is adjustable to allow different stud types to be used and wherein absolute clamp-up is provided through repeated cycling. A spring loaded lock plate that captivates the quarter turn cross-pin in the locked position against the adjacent cam surface is provided. The lock plate is positioned within the receptacle and indicates the correct locked position at absolute clamp-up when the lock plate snaps over the cross-pin. Two ramps on the lockplate provide a positive “feel” when installing or removing the stud and provide the detent/lock feature. The cam comprises two helixed ramps leading to flat surfaces or plateaus for the cross-pin to ride up and tighten against. The plateaus are adjacent to detent recesses on the lock plate which provide the locking capability.
