(10 Pieces) Floating Shelf Brackets Heavy Duty Wood Invisible Shelf Brackets with Screws,DIY Adjustable Hardware Blind Supports Shelves 120LBS

Works great for me attached to my reinforced concrete walls!From my understanding, these anchors are meant to be used on solid/block/concrete walls where you drill a hole and attach these bolts which expand like wall plugs with fasteners. Many reviewers are complaining and leaving poor reviews because they don't understand this and have clearly bought the wrong product for their use case. These will not work on drywall/sheetrock.

My window to return these has passed so I'm stuck with them. Just a warning to anyone looking at this specific bracket. They do not work. I have three huge holes in my wall now. The installation instructions are vague and the y should work but they don't. If you get it in the wall and lose the stabilizer - it's over. Junk. Do not recommend.

I assumed I could use these with and without a wood stud. You rarely get lucky to have access to 2 studs for a shelf. But it turns out that these don't actually work at all for studs because of the type of screw and built-in anchor. This probably effects how much weight it supports, but for me it was fine. The other thing that's weird with these is that it's difficult to get the anchor started so that it's not slipping in the wall. I used needle nose pliers to hold the anchor while turning the piece that sticks out for the shelf. This compresses the anchor and causes it to flange out and grab the back of the drywall. Once it grabs tight enough, you can stop using the pliers and push the anchor fully into the wall and finish tightening the anchor fully. I installed 2 and then measured carefully for with my shelf and drilled the holes into the shelf. You have to counter sink the holes because there is a flange and washer on the end of the anchor that will stick out otherwise. It was a snug fit and feels sturdy for decorative nik naks on my floating shelf.

I'm a general contractor. More customers are asking me for floating shelves. I decided to try these brackets. My goal was to cut custom shelves from 1x4" or 1x6" pine trim boards.In short, they work great when screwed into studs. They work terrible when fastened to sheetrock.As others reported, when fastened to sheetrock they are loose and wobbly.Sheetrock (in the USA) is generally 1/2" thick for walls. The problem with these brackets is that the plastic piece that is inserted into the sheetrock doesn't swell enough so that it bulges into the sheetrock. I was able to use a pair of needle nose plyers to grasp the plastic piece while I screwed in the screw using vise grips. It was very difficult to do this but it did make a positive difference. It caused the plastic piece to swell out more. However, the overall effect is that it's still a bit loose.For another installation where studs were located in a convenient position, I omitted the plastic piece. I instead used a cutoff wheel to cut off a portion of the metal screw (left about 2"). Then I drilled a slightly smaller hole in the stud so that the screw could fasten into it. Then I used vise grips to screw in the screw to the stud (used 2 screws). I was able to make adjustments to the level by tapping it with a rubber mallet. This approach worked very well. The shelves are super steady.Drilling a hole into the pine 1x4" or 1x6" trim so that the bracket slips into it tightly was easy. No problems here.Overall, I think the manufacturer needs to improve the design of the plastic piece so that it properly swells into the sheetrock when the screw is fastened into it. This would fix the problem.

I didn't see the dimension size in advertising. It is too big for me.

Wanted to put up a 7/8" thick board as a floating shelf, this worked fine. Only thing, use a drill guide and really need metric bits.

In theory, this is brilliant. In practice, the screw has to be turned SO TIGHT that there is no way this could ever anchor in drywall. Just as a test, I held it with pliers and turned it with a wrench to see if it could theoretically be made to work, and even when completely crushing the plastic the wings still did not spread out. Look elsewhere.
