Bought some shelves from Ikea and it looked like the shelf would collapse if the fastener wasn't on the stud. Then I saw these things and decided to give it a try. They are very easy to install and once installed they look great thanks to the pressfit socket. The shelves were installed and seemed so solid as if I had tightened the pins on all the screws. I use a different project box just in case. Tip! Drill a hole with a 10mm bit (or equivalent in inches) and don't think 9mm is so good. It is not. :)
