I purchased this item as a replacement for the finials on my Rod as one had become damaged. I have a 1β Rod. However when I received them they could not be used on my Rod. The screw on this denial is thin (seller says it is standard size), however it is too narrow for the nut in which it should screw. My previous fenial screw size is 1/2β. It would be helpful if seller stated the size of the screw instead of the size Rod it will fit as I even though I have a 1β Rod, this item will not work with
