2 Slot Cast Iron Flange Question

[stevetone]

Forgive me if this is a real basic question...First post by a newby!

I am installing a new toilet onto a cast iron flange. The flange only has two half-round "cutouts" on each side for the closet bolts not the wide-then-narrow slots that I see on most newer flanges. The closet bolt heads just sit in these cutouts between the floor and the bottom of the flange.

The challenge is that the closet bolts spin rather easily when tightening the nuts, as there is nothing to keep them from doing so.

My question is: Is this normal, and if not, what is the remedy?

Usually you can get a head that will not rotate, but that being said, it's probably easier to get a thin nut and anchor it to the flange, then the wax and the toilet. that way, the bolt is tight and won't slide around.

Plumbers buy the bolt sets with four nuts and four washers.
That way you can fasten the closet bolt to the flange before the bowl is set.
If you have to cut a bolt down, there is nothing worse than the bottom end slipping out, pulling the bowl and starting over again.
The home centers don't sell closet bolts with that many washers and nuts. It's a plumber thing. We would rather spend a bit more, and not waste our time pulling bowls up.

I have the same problem ...slots are bigger than bolts head ...you said buy 4 nuts and 4 washers ...so I believe use one washer and one nut to connect flange to bolt and than use another set of nut+washer when u put bowl correct?

So you are saying put a thin nut on the closet bolt when u put it on the flange (before installing bowl) so just secure closet bolt to flange with a nut (instead securing it after putting the bowl) correct? and it has to be think otherwise toilet will wobble?
