Replaced the fill unit in my toilet and when re-opening the supply I got a leak at the valve stem. General rule of thumb is to first try tightening the packing nut but this valve doesn't seem to have a standard, female threaded nut. Instead the nut is male threaded. I tried tightening this and it did stop the leak but I had to apply a lot of force. So what is the anatomy of this valve pictured below?
