Tom, could you please explain, why bolts rather than screws will be better with repect to leakage? As an engineer I would say that the pressure between the connected parts, put on to the gasket, will seal everything. And the pressure will be the same using bolts or screws, just depending on the torque on the screws/nuts. Thanks for any further insight.
