The end fastener provides a xed, 90 degree, moderate-strength connection that is completely hidden. The winged tabs of the clip prevent the mating prole from rotating. This connection method requires two machining services; an end tap on the mounting prole and an access hole in the mating prole in order to reach the screw head. Additional Information: Wing clips are available separately (without the button head socket cap screw) for instances where you want to create your own custom assembly.
