> I am building the valved reflux home still that I downloaded from moonshinestill. com. The construction is almost complete, but I am having trouble finding a "threaded fastener nut". I have no idea what that term means and I have been unable to define it after a few hours internet research. I have checked at all my local hardware stores and no-one has any idea what still designers are talking about. Can any one tell me what a "Threaded Fastener Nut" is and where they can be purchased. Thanks
