Neodymium Rectangular Pot Magnet with Countersunk Hole and Matching Screws - 60x13.5x5mm, 10 Packs

I got these to mount in my shed to hang a few small gardening tools. I even used one on the outside of the shed to hold the door latch so the the wind doesn't blow the door shut on my, as it is prone to do. The mounting screws could be a bit longer in my opinion due to the extreme strength of the magnet. Over time the screws may pull out, but for now they're holding just fine. I can always replace the screws with longer ones. Keep your fingers safely out from between two magnets or you will live to regret it. ;)

Very strong.... I use these for gun magnetic holder for my cars and in hideaway places... In the car the gun will never fall off... Can't pull straight off cause the hold is too good... I slide or lean the gun over and then pull... Get 5/8 heatshrink put it over these and you've got the same as the $20 gun magnets for a 10th the cost

Theses are very strong, conviently counter sunk, and in a U channel. In other words: exactly as advertised. Unfortunately I didn't read carefully and thought they would come paired as 5 N up 5 S up. But they are all 10 polarized identically. This precludes using them as magnet-magnet closures.It's kind of dumb to not ship pairs so only 1 stars.If your application is magnet to iron attraction than my complaint is irrelevant. And you could use these.

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!

Amazon, please update the items you want ratings for. None of the reviewable 'items' are relevant, so I will make my own: Construction, 5; Rated Strength, 5; Functionality, 5. What can you say about a magnet? Right? Actually, there are lots to be said about magnets. For simplicity sake, the first is the rated 'pull', i.e., how many perpendicular 'pounds' of force does it take to remove the magnet from clean, unpainted iron.... So, the user needs to determine what they are using it for. For example, you wouldn't probably want to put a 100lb bar magnet on a shower door or most cabinet doors or 80lb magnets to hold pictures, etc. to your refrigerator. However, in earthquake proned California, you might consider a strong magnet to keep kitchen cabinet dors from opening during the shaking to prevent your glasses and dishes from crashing out (functionality) and, (construction) magnet housing not made d enough to prevent the magnet from coming out of its 'holder'. With 'inquisitive' grandchildren around now, I found stong magnets keep them out of certain drawers and cabinets; works better at a fraction of the cost of some 'fancy' "child proof" device. These magnets (housing) and 'striker' plate are consistent in their fabrication and assembly. The strength is close to rating (using uncalibrated pull weight scale). Functionality... is whatever you can imagine a use for them. In my case, I attach them to the tops of tool chests, etc. to 'hang things'. Approximately ⅔ of the magnet sticks above the cabinet. Clamps, test equipment, etc. are 'hooked' over the top. In the kitchen one similar use is hanging large UV wands for easy access for counter and equipment final sterilization.
