These anchors are tough. I put a 3/16" concrete screw through one and the anchor expanded nicely, and without bursting (see second photo). The large quantity (100 pieces) will ensure that I now have plenty of anchors for work in the basement. Hint: when opening the container, remove the staples on one side only. Then you will be able to easily snap the container closed later without losing any anchors.

I ordered these anchors to try to reattach a problematic outside door that keeps coming off because the hinge was screwed into a hollow metal frame. I have used more traditional flared-end anchors in the past, and those hold for a while before the door falls off again. These anchors are not flared at all. I had to drill bigger holes to accommodate the width of the anchors, but when I tried to use them, they simply pushed into the hollow frame and would not take the screw. An anchor with a flared end will at least hold onto the outside of the frame and allow the screw to go in and stay for a while. I can see these working in a wall or doorframe where the drilled hole has a finite depth (so they don't get pushed all the way in and fall into the wall or doorframe). I don't know if these will serve any purpose in my home due to their weird design.

Perfect execution on a simple concept. Yes, these are wall anchors, there's much to love and not much to hate about them, they work as they should - you drill a quarter inch hole in concrete or brick, stick this piece of plastic in and it'll hold a screw perfectly in the wall. The size is accurate at roughly 1.15 inches and quarter inch in diameter, the plastic is relatively elastic so it'll expand to wrap the screw threads without being brittle and crumbling off. Extra length that doesn't fit in the hole can easily be cut off with a utility blade. Nothing wrong with these wall anchors at all and it works as expected

I needed this for a small project. They are hard and rigid, just right for the two small holes I need to make in concrete. Any thicker and I don't think I could have drilled through it. You do get a lot, so I am hoping I can also use this in other areas around the house. I'm not sure they would work for drywall, but anything outside with stucco or brick or masonry work they should be fine. I do see what others have said that on one side there is just a little plastic nib, probably because they were created like a plastic model where they were connected with tabs and had to be removed. Overall, if you need a small concrete anchor and a lot of them...these should work great.

Pros:- Dimensionally accurate- High quality strong plastic- Very good grip if installed properlyCons:- Does not expand as much as other types of anchors. It does expand to get a good grip but you will need to drill an accurate sized hole.

Just tested it without even putting it into the concrete wall, the anchors barely changed shape while driving a screw into it. Save your money.

These are hard plastic sleaves not flexible drywall style perfect for my needs of mounting security cameras on the brick exterior of a school since these are hard plastic a screw actually expands the sleeve nicely for a snug fit. I read a review where someone tried using these in a hollow frame and I would agree that these are not the style you would want in that scenario but for brick/masonry/concrete this is what you want. Value for price.

Discovering this product gave me the idea that it might be a solution to a particular issue I was facing. I have steel roofing on my home, screwed down to wooden lath underlayment. Over time, with snow loads and seasonal thawing, etc, many of the screw holes were becoming stripped, so the screws couldn't be properly re-tightened to the roof. And loose screws in steel roofing = leaks. I got these Expandet screw anchors, hoping they'd let me get everything down snug again.The product states that one needs to drill a 1/4" hole, then hammer in the anchors. The screw holes in my metal roofing, as installed, were 3/16". As a test, I drilled out one of the existing holes to 1/4" and tried tapping in an anchor. I soon discovered there's no way it was going to go through a hole that size in a steel panel. The outer edge of the plastic would simply butt up against the rim of the (apparently undersized) steel hole. More aggressive pounding merely caused the plastic to start peeling away from the edge of the anchor.So I figured "Okay, that's too small." And I tried enlarging the hole bit by bit (no pun intended). Going up to 9/32" still wasn't enough. Finally, a hole of 19/64" allowed me to get the anchor in. I reached for the screw to start tightening it down, and... well, you're probably way ahead of me. All that happened as I tried to turn the screw in was that the anchor spun around and around within my clearly over-sized hole. Utterly useless. (And yes, I did feel a little foolish for not realizing how obvious this result was going to be before I tried it.)But wait, I thought. A lot of people seem to be using these anchors with success. So I simplified my experiment: taking a scrap piece of softwood lumber, I drilled a hole of the prescribed 1/4". A little light hammering did in fact succeed in getting the anchor into this board, and it held fast as I ran one of my roofing screws right into it.The product description for these Screw Anchors lists almost every material you can think of as being a suitable use. My own limited experience says: softwood lumber - YES, metal roofing - NO. Of course, I do have a workaround: I can drill out the screw holes in my steel roofing to a full 19/64", allowing the screw anchor to pass through, but then use a 1/4" bit to go into the underlayment, where I can expect the anchor to hold firm. And because it does work in wood like this, I think the product deserves 4 stars. But the two-step drilling I'm going to have to do for each and every screw I re-set in my roof is going to be a chore.I'll leave it to others to do their own research with concrete, masonry, drywall(?), tile, plastic, etc
