BullfixExtra Heavy Duty Drywall Anchors, Holds up to 293lbs, Hollow Wall Anchor Mount Set with Screws Included, Stronger Than Toggle Bolts and Butterfly Screw - Patented Design - Starter Pack

I ordered heavy glass shelves to hang in a corner but, once I started drilling into one of the walls, I realized there was an air duct directly behind it. There is a little less than an inch between the drywall and the duct, which meant that any traditional anchor would be too long or unable to support the weight of the shelves. I searched everywhere for a solution, and the only one I found was to open up the wall, attach a piece of would between two stud, replace the drywall, repaint the wall, and screw into that. That wasn’t an option for me, so I hopped on Amazon to search for a miracle. These anchors looked secure and designed well, but I realized right away that the included screws would be too long. I purchased some shorted screws with the same diameter and got started. Installing the anchors was a breeze - in my case, I didn’t have enough room to pop them in easily because of the limited space behind the drywall, but the air duct had enough flex to allow me to wiggle them in. Once installed, they worked perfectly. My heavy glass shelves are secure, even with an extra pound or so of items placed on top. VERY happy with these anchors!

Worked exactly as advertised. I needed to mount a TV on a wall of drywall with a small gap and then cement block ("cinder block"). Other high-weight capacity anchors I had couldn't reply properly in the gap, the gap made using concrete anchors unworkable since I am not in a position to open the wall and fill the gap. These went in easy and are holding well.

Excellent product. I used it to mount my large jewelry armoire to the wall. It is much sturdier than the regular drywall plastic inserts.

Someone used VERY thin drywall in our house. Getting any screw and anchor system to hold was a joke. However these went in tight and stayed tight. We have a peg board that holds all of the controllers for all of our game systems. As well as a usb hub and the charging wires for all of the controllers. Oh and lights for esthetic and this board does not budge. A GREAT product.

Anchor seems holds strong on 1/2in sheetrock but you have to use their provided screws because the anchor has predrilled holes. This isn't a huge problem except the screws are a little big so it's not for every project. I'm not sure I'd trust it for serious weight like the info says it is rated for 293 pounds, but at least 20 or 30 which is plenty for most things.*update* changed from 3 star to 4 starHave used these for several projects now. They're quite solid. Certainly a pain that you have to use tge provided screws. But I'm pretty impressed. They even hold in lathe and plaster walls.

I have a stair rail that no anchor from Home Depot or Lowe’s would hold for more than a month, eventually deteriorating as they would not tighten up. These appeared to be the best available, so I tried them. Easy to install, though you will have a rather large drywall hole so measure and mark well as you are not going to move them over a bit if you fail to do so. Once in, they fully tighten and my stair rail is solid. Recommended.

Bought these and was super really excited to use these b/c I thought they would work really well for towel rack and a curtain rod. Unfortunately, every time I attempted to install it, it dropped into the wall and disappeared. This happened 3 times until I finally gave up. I used the old school wing nut ones, which worked perfectly. I won't rule out that I was doing something wrong, but I'm 99% sure I did it correctly and the product simply didn't work.

Easy to use and feels very strong
