BullfixExtra Heavy Duty Drywall Anchors, Holds up to 293lbs, Hollow Wall Anchor Mount Set, Stronger Than Toggle Bolts and Butterfly Screw, Drywall Anchors and Screws Kit - 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!

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.

Easy to use and feels very strong

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.

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.

These anchors are amazing. They are so easy to insert and hold a lot of weight. I had some cabinets that wouldn't line up with a stud on one side or the other so I used these where I couldn't screw into a stud.I lined the cabinet up where it needed to be and then drilled a hole through the mounting board into the wall which left a mark for the anchor placement. I then took down the cabinet, drilled the hole for the collar where the previous drill mark was, inserted the collar and the anchor and then put the cabinet back in place and screwed it in. This lined up the screw with the anchor perfectly and held the cabinet securely in place. It was a lot easier than toggle bolts or going with a costly rail mount system. I will definitely be using these for other projects.

I received an open, used package. Three of the fasteners were correct but two were used. One of the four was another type entirely, also used. Of course the bit was used as well. How pathetic can you get?

Super easy to install, definitely buying more for future home projects. Feel like I can trust the lbs for the projects I was doing. Also great if you mess up on a different anchor. This is big enough to fit most holes.
