Would these be strong through 3/8" or 1/2" glass? I need better magnets to hold up a turtle dock in my turtle aquarium.

I tried holding a half box of personal note cards on one side of a piece of 1/2 inch wood with a single magnet on one side and four on the other. It kept sliding down when I got near vertical. You can try but I think the magnetic might only keep it in place and relatively easy tugging or pulling would be enough to move the dock. These magnets don't want to be placed side to side or edge to edge. They snap together into a stack real fast. On the side of a refrigerator they need to be slid off. So wrap a piece of tape on then to take them apart easily. I also tried holding up a box of paper clips on one side of the 1/2 inch wood and four magnets on the other side and that didn't work at all.

I just took a magnet to them. They are magnetic. We have a 1/2" drill, but yes they would fit in a 3/8" drill too.

I used them to secure sliding class windows from being opened. It may depend on how your mount is anchored. I suggest you contact the seller and ask them.

They work great for holding old glass tube TV's on stands to the wall. It attaches to the item you want to attach to the wall with think adhesive on nylon straps. I dont think they could be depended on to hold onto a smooth glass aquarium weighing a hundred pounds with water. I would not do it. The other end attaches with wood screws in studs. Though it would be better than nothing, I would not trust it.

Ir will hold it up, my concern would be is the glass strong enough to keep from breaking. I would hesitate to use it on anything thinner than 1/2" and wouldn't put anything heavy on it.

Hard to tell as I only have the screw ones in my home. The magnet's are pretty strong so they might work THROUGH the plastic cover...the best way to test this is if you have a magnet laying around (like on on your refrigerator). If the magnet will stick to the switchplate there's a pretty good chance this will work.

Can't say for sure, but my guess would be yes since these magnets really are so very strong. These are not the same type of magnets you would find in a tourist trap when buying refrigerator magnets for souvenirs. These little suckers are much stronger

I would guess anything over 3/16 - 1/4" should be fine. They use two screws to mount on each side. As long as there is enough room for a small screw, as they mount one over the top of the other.

They are very strong magnets but you may need a few for a 3 pound tool. Will definitely work well for screw drivers, wrenches, pliers, and ratchets. Hammers may require 2 depending on the weight.

Strong magnet shouldn't be a problem. I anchored mine at the bottom with extra strength Velcro. Love it may get a second!

Yes! You want "rare earth" or "Neodymium" magnets. They are STRONG and tough to pull apart. We like the 3/8 inch to hold 1-2 pages (B000E67ZO4) and the 1/2 inch to hold more/thicker pages (B000UCWU38). Good luck - and keep them apart on the board or they will "smash" into each other!

only if they are short shelves. 1/2 inch is about half the strength of 3/4. The sides may bow after time. I would not use 1/2.

I can tell you that they stick well to my refrigerator and magnetic whiteboard. I am not sure about glass unless the glass is somehow magnetic.

they are pretty strong, approximately 1/2 inch thick. I use them pretty much everyday as I have granite countertops.

I bought these to hold glass in door frame but have not completed project. Sorry I cannot help you.

They are really smooth on the outsides but I would think it would depend on what you were using the magnets to stick to fridge. I know they are surprisingly strong!

I'm using them on a 1-1/4" rod and they fit. If the rod is 2" there will be a gap which can face the back of the closet if you are okay with that. They work very well for sliding hangers. My old rods were wood and gave me splinters.
