LOVIMAG Neodymium Strong Bar Magnets with Screws Holes 10Pack, 80lbs

Much stronger than expected! They countersunk the magnets should have the bases

I bought a set of ten 60x13.5x5mm bar magnets. I've long felt that countersunk rare-earth magnets were the best way to attach them so that they don't transfer their attachment to the object you were hanging. These come with nonmagnetic screws -- small, but they do seem to work -- and the magnets are cradled in a steel chassis. As many reviews have noted, these are fragile bars, especially at the point of the countersunk hole. If you pry the magnet away from a steel surface, the bar can crack at the hole and even leave the short end behind. But if you slide the magnet sideways off the steel surface, you'll likely keep the magnet intact. I keep finding unexpected uses for these. I needed to hang a dustpan under my sink, but all available places for a cuphook were taken. So I screwed a hook onto a small block of wood, then screwed two of these bar magnets onto the top of the block, which now adheres to the underside of my cast-iron sink with amazing strength. In similar fashion, I have a broom with a metal handle that wouldn't stop detaching itself from a retainer clip on the inside of a cabinet door. One of these bars is now working very well to keep it in place. Recently, however, I discovered that my stack of magnets had one bar on which one hole wasn't countersunk. I reported it to the seller, and I was pleasantly surprised to be offered a prorated refund, along with the most courteous of greetings. Hope to do business with this seller again!

Recently moved into a house built in 1965 and replaced all the HVAC vent covers bcuz the old ones (probably the originals) were so over-painted and ugly. (Don't you just hate that)? The old ductwork wouldn't hold the screws for the new vents and I didn't want to trust them to only the drywall or have to patch/repair drywall so screws would hold, so used these magnets to hold the new vent covers in place. Screwed 2 to the top of each duct opening and so far they're working just fine. The hardest part was drilling the holes in the duct while laying on my back. The problem now is how to deal with "hiding" the screw holes on the room/exposed side of the vents because the screws aren't being used to secure the vents to the walls. The plan is to epoxy the screws in place, then cut them off from the backside of the vent so from the exposed side they look as if they're screwed into the wall, but will be there just for show to hide the screw holes in the vents. These make for easy removal & replacement of vent covers. (With the magnets, when removing/replacing the vent covers for any reason, don't have to worry about screws being held by only drywall). This approach was much more expensive than using just/only screws, but if the screws wouldn't hold the vent covers in place, they were useless, and these served my purpose. (Wondering why new construction doesn't use magnets instead of weak, poorly-working screws that eventually don't hold the covers securely).

I ordered a few of these to test the strength on and let me tell you, if you directly attach something to the magnet, you'll have a hard time getting it back off--EXCEPT if you attached it on the steel side. The strength of direct contact is extremely high, but if there's anything placed in the way the magnetic field drops off incredibly quickly. Additionally, these are magnetized on the flat sides--not the ends. This means that it's super easy to stack them on top of each other and never ever separate them, but if you want to create a magnet bar you'll be fighting the poles the whole time. Not ideal when you're making a tool holder. Overall 4 stars, though it would be 5 if the poles were at the ends of the magnet rather than the flat sides. Depending on what you're doing these are either great or useless.

These magnets are very strong and easy to mount. Mounted them n boxes to attach to electric pallet jack battery lids for pickers so they can carry their personal affects while working. You can't exactly lift these off the battery lids, you have to slide them off which is great. They are however a bit brittle. If you slam or drop the boxes with the magnets mounted they will fracture pretty quickly. Obviously this isn't the intended use, so there's no issue here. But if you're planning on continually removing the magnets from a surface, (while not really being careful about sliding them off) these probably won't last long for you. Besides that, they're really strong.

Powerful

They are very strong but brittle

Very strong magnetic for it size

Awesome magnets. Not a whole lot to say other than: so strong! This is not your crappy fridge magnet. This magnet is on its own level of strength. If you need a magnet that will hold and not move, hold something heavy, etc this is it. Used it to hold curtains in place in our van and they do not move or let in any light now. Nice that it has mounting holes too.

Pros: Very powerful magnets. Cons: They are fragile and will break if you drop them.

These are as expected. They cannot be easily removed from the metal "housing" so strong magnet side is the exposed magnet side with the screw heads. Not an issue in my use case but maybe in yours.

I used these to hold a basket for groceries on the back of a bicycle. So, very strong. I can lift the electric bike up with the basket. To release it from the the bike I have to give it a quick jerk to break the grab.

Super magnets. I used them to make wall mounted knife holder. These were strong enough to hold the knives through about 1/4 inch of wood without any issues. Definitely capable for a ton of different projects or applications.
