Nice double expansion anchors. They work great in spots where regular single expansion anchors don't work as well like hollow block. Nice that they are marked with both the bolt size and drill size on each one.

I used these to anchor out canopy on our patio and these work extremely well. you can also remove these when not needed anymore which you can not do with other concrete insert anchors. Good item.

Got these for my fifth (?) attempt to securely mount a flagpole holder to my stucco house. Unlike all the other anchor solutions, these grabbed securely and stay in place. I have a bunch extra, but still worth it.FYI: the thread pitch is 20. So I paired these with 1/4-20 x 1-1/2'' screws.

Great price for the number sold. Using these to install outside wall Minisplit hangers (holding up to about 150 lbs using three of these) Work out very nicely. IF you are putting these in brick or concrete, I might suggest getting an inexpensive SDS+ hammer-drill (also available thru Amazon) and the correct SDS+ bit to install. Cuts the drill time down to about 2 mins for a 2-3 inch deep hole....THESE are the CATS MEOW for that type of installation. PRICE IS GREAT. Quality is sufficient for this type of application. When I run out of my second 25 (had purchased 2x) will be ordering from this seller again. PRICE IS GREAT compared to the chain hardware stores or fleabay sellers.
