The Moroso self-ejecting quick fastener in aluminum with a black finish is a 7/16in fastener with a .550in shank, sold as a 10-pack. Its longer shank fits layered or thicker materials while the self-ejecting mechanism simplifies removal. The aluminum body reduces weight and resists corrosion, and the black finish keeps a discreet appearance for visible fastener locations in fabrication or maintenance work.
