They are NOT 4 1/2 inch but actually 4 9/16.  I will have to do some finagling to get them to work but I don't mind tooo much since they are very pretty and will really update my old furniture.  This is a hard size to come by so I will have to make do. Came with 1" screws so I have to locate shorter ones that will work for me.  A lot of effort but I think it will be worth it in the end.
