I had a leak around this plug and replaced one assembly and now the second one is leaking.

A couple of questions.

1) The wings are bigger than the opening, how do you get the black hex head in place on the radiator?
2) Why do they call this an adjusting screw? It seems to leak variably based on the quarter turn of the black hex head.
