I use these everywhere
Most things you want to mount to a wall probably aren't very heavy. Even that huge, ugly painting your relative gave you and you don't have the heart to bring to a swap meet probably weighs at most 20 lbs. The problem is usually just that you...just...can't...get...a...freaking...nail...into...the...wall. That's where these things come in. They're tiny, they're strong, they work in everything. I've used these on drywall, lath-and-plaster, cinder block, clay block, concrete, and soft wood. (I guess I mount a lot of stuff, heh!) Pair them with a small cordless hammer drill and you'll be hanging things in your unfinished garage and basement like you were born to do it.

Its worth it a couple cents for peace of mind.
Ive been using 1 inch drywall screws and these for a majority of my installs and haven't had any issues with them. 4 in some 1/2 drywall and I can hang off a towl rack i weigh 240.

Caution about the size listed, not what you're going to get.
The anchors will work fine for other projects but the size listed is not what I got. They list it as 3/16" that is the hole you need to drill not the size of the screw. On the box the screw size is a #6 much smaller than 3/16 and much to small for the .2" screw I needed them for. Order according.

Gr8 Things come in Small Boxes
The product arrived in a day. It was in a padded envelope, the box of anchors inside was wrecked. I had to tape it back together. I tried the product on a side wall I made up for a hot air solar panel. I glued 5.2mn overlayment to polycanurate foam. I then drilled 1" deep holes 3/16 in diameter every 4" inches into the panel. Into the holes inserted the anchors. They hold awesomely. I am now able to screw down the flashing into a wall made of insulating foam. The anchors will take a #8 screws. Awesome product GR8 value less than 13 cents an anchor👍👍
