Review on FramingSuppliesFast 1/8 Offset Mounting Canvas Z Clips for Picture Framing - #6 X 3/8 Pan-Head Screws Included - Pack of 100 by Linda Diaz

Worked great, screws included. I would suggest getting different mounting tab depths to expand frame options. I found many frames that I liked and fit my budget, but the tongue and groove depth was too shallow and I could have used a .125 or .25 mounting bracket, for example. Although I prefer hidden installation. I use plasterboard and the brand I use is half an inch thick so frames in the style I prefer are harder to find. This is a good flush mount product, I haven't tried it but I think it can be bent slightly to accommodate different tongue and groove depths.
