#8 1-1/4 Gray Ribbed Anchors with Screws (100-Pack) is rated 2.8 out of 5 by 17.
Rated 1 out of 5 by from Does not work as intended As you thread the screw into this anchor, all it does is pull the anchor out of the wall toward you. In fairness, two of them did support a 40 lb shelving unit, but I took it down as soon as I saw that the anchor was hanging a good half inch out of the wall. In short: do not buy.

Rated 1 out of 5 by from Does NOT work!! Good in principle and looks nice in the picture - but doesn't work AT ALL. Even worse than the standard plastic wall anchors. DO NOT BUY!! Stick with the most popular threaded drywall anchors.

Rated 1 out of 5 by from Anchors did not open I walked into the bedroom one random day months after using the anchors to secure shelves to the closet wall to find that everything had fallen to the floor. What I found was that the entire anchor and screw had pulled from the wall. The weight on the shelves was well within the limit stated on the package. What I found was that the anchors did not open at all. Now I have to re-evaluate everything else I have hung using this product. Less than stellar, sub-par, and lousy.

Rated 4 out of 5 by from Pretty Good; Some Practice Helps Hope this isn't a duplicate review; was finishing one when the page reloaded for some reason and lost it... Anyway, bought these for a project (shelves, towel racks, etc. in a small bathroom) before reading the reviews and was having doubts after I read them. Never used them before. Thought I'd return them but the design looked good so decided to try the anchors on a piece of 1/2 inch drywall scrap before actually using (or returning) them. First thing I found is that the tip of the anchor gauges at 1/4 inch but the supplied drill bit gauged at 17/64 and it made a kind of sloppy hole, and did not exit the back of the drywall very cleanly. An old (wasn't going to use a good bit on drywall; that stuff would ruin it) 1/4 inch bit made a much cleaner hole, even out the back paper of the drywall. Then I tried the anchor itself; the 1/4 inch hole from the old bit was just right. Next came the screw; once the screw was all the way in and the screw head contacted the surface, I found after some trial and error that 5-6 turns expanded the anchor and set everything as it should. Finally, when it came time to actually using them on my project, I put a dab of caulk in the back of the hole before inserting the anchor. Conclusion: They're pretty easy to work with. I found (and recommend) practicing with the anchors on a drywall scrap to get a feel for them before actually using them (made a world of difference, for me anyway) and to use a 1/4 inch drill bit (not the one they include). The anchors seem to be doing the job and considering the cost of a pack of 100 I think they're reasonably priced.

Rated 1 out of 5 by from Worst anchors I have ever used... I have been hanging a lot of items on my old plaster and lathe walls lately and have tried a few different type of anchors to get the job done. But these... they are the worst anchors I have ever used. Even if you drill the absolute most precise hole to put them in they will not go in all the way. Normally not a problem, you just give the anchor a soft tap or two with a hammer till they are flush with the wall and all is good. But not with these guys! The top end of the anchor is very flimsy. A single tap with with a hammer or even a firm push with your finger causes the entire exposed part of the anchor to collapse, rending it smashed, useless and requiring a pair of needle nose pliers in order to remove it from the wall. I was lucky to get one in every four anchors to work. In the end I went back to the cheap generic style screw anchors that you can find in every hardware store. They are a heck of a lot cheaper and work ten times better!

Rated 1 out of 5 by from Very poor. Why doesn't home depot try out what they sell in the stores? Very Dissapointed... The plastic is so cheap that the screws can easily pull through the threads in it. It cannot hold more that a pound or two before this happens. I bought it in the store thinking home depot would checkout and sell good items... I was very wrong.. they likely only selected what to see based on the profit they could make. I bought two different sizes of these in larger packs for about $12 each... What a terrible waste of money. I am off to Amazon to get a real product that is useful. Since I've used one of each (they couldn't pull out so I needed to tear the ends off and lot the other half drop back into the wall) there probably isn't any way for me to get my money back :( Very bad product and I am quite experienced at home repairs and projects so I am guessing the reviews that are positive are fake. I highly recommend to not purchase any products from "Triple Grip"

Rated 1 out of 5 by from Taking them back These shouldn't even be on the shelf. I've used many dry wall anchors and these fall in the category of the junk you get free in some packages that usually get tossed for better.
