Your best bet is to try a home center or hardware store. They will sell steel circular brackets for closets. As long as it fits the bar and is rated to hold your weight, just make sure to use long screws to make sure it get all the way to the stud.
Reply:You can use a pipe flange. Even though it has threads on the inside, select one that fits your needs. Just go to the hardware store and ask the clerk to show you the pipe flanges. They come in different pipe sizes.
