ANUIMOAR 30 PCS Outdoor String Lights Hooks Plant Q-Hanger Screw Hooks for Hanging Christmas Lights, Plants, Wind Chimes, Ceiling Hooks with Safety Buckle, Windproof, 2.2 Inches

So long as you know these are not able to handle much more than 20 lbs, these are outstanding screw hooks with a nice safety clasp that keeps things in place. They work in both ceiling and wall modes, and I am currently using them in the wall of my shop to hold tools and parts. What I love most about this set is the driver that comes with it, and makes it a trivial process to install the hooks. The anchors that come with it are not very good, and I recommend you replace them with higher quality anchors if you plan to use these in wallboard. These can handle 40 lbs only if installed into a stud in the ceiling. In wall mode, best to limit objects to 20 lbs, especially if not installed into a stud.
