Liquid-tight structure with a fastener component
A liquid-tight structure includes a stepped fastener having a first shank and a second shank. The stepped fastener is threadingly engaged with an opening that includes a first step and a second step. A first diameter of the first shank is larger than a second diameter of the second shank. The liquid-tight structure includes a first seal seated on and in physical communication with a first top surface of the first step of the opening. The first seal is compressed between a first side of the opening and the first shank. The liquid-tight structure includes a second seal seated on and in physical communication with a second top surface of the second step of the opening. The second seal is compressed between a second side of the opening and the second shank.
