The double wing clip is commonly used with two button head socket cap screws to create custom end fastener assemblies. The winged tabs of the clip prevent the mating profile from rotating. An end fastener connection method requires two machining services; an end tap service (creating two parallel through holes) on the mounting profile and two access holes in the mating profile in order to reach the screw heads.
