Yes, they have been used to hold light floating shelves, but again, make sure that the surface you are using is as recommended and the shelf is well within the weight limit. Don't forget that you will be placing some items on the shelf, so a good practice is to weigh both the shelf and the objects together first before installing. Alternatively, you can consider getting the Command Picture Ledge which can hold up to 5lbs and have all the necessary tools included.
