The Moroso self-ejecting quick fastener in aluminum is a 7/16in fastener with a .550in shank, sold as a 10-pack. The extended shank is useful for thicker panel stacks while the self-ejecting feature eases removal. Aluminum construction lowers weight and improves corrosion resistance compared with steel, making this variant suited to applications where lighter fasteners or reduced galvanic concerns are preferred.
