They'll work, but you may not get the "O" Ring to seal properly. The SNS fitting for RG6QS has a black plastic piece. It's a small difference, but if you are doing many of them, it's gonna be easier to use the right fitting and get a good crimp on it.
Good Luck!
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!
