80/20 Inc. For the most up to date information on 80/20 products visit 8020.net 218 Fastening Methods FASTENERS Single Tab End Fastener Part Description: The single tab end fastener assembly is comprised of a button head socket cap screw and a single tab wing clip. The single tab end fastener provides a xed, 90 degree, moderate-strength connection that is completely hidden. The single winged tab is used for closed face, radius and angled proles; the winged tab prevents the mating prole from rotating while the straight end is ush with the mounting prole. 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.
