Buy washers and use them on hollow core backing screws

This product solves the problem standard with the hardware that comes with folding doors. It replaces the painted knobs and covers the painted surfaces behind the knobs. This improves the appearance and reduces the need to repaint frequently used door knobs and surrounding surfaces. Installation was easy and delivery was excellent.

These were very easy to install. Look great against my whore bifold doors. Easy to grip to open door

So happy I purchased these to replace the wooden door handles that came with the house (picture and video attached).

Very cute. Nice upgrade to our closets that had old wooden knobs. The screws could be a tad longer though. Will probably need to get some longer ones eventually but for now they are on and look nice.
