Review on 🔩 Hollow Wall Anchor Kit - Complete Set of Screw-in Drywall Anchors for Easy Mounting, Including Self-Drilling Fasteners by David Dortch

The description of these anchors does not mention the wall thickness they were made for or the required hole size and no instructions accompanied the product. I made a purchase based on the picture shown. I ended up drilling 3/8" holes and found it worked well. So far I've used them for 1/2" drywall and it has worked well. my next use will be on 5/8" thick drywall as well as porcelain tile over drywall. I'm hoping these anchors will hold the extra thickness of the wall.
