DIYMAG Strong Neodymium Rectangular Pot Magnets with Counter Bore, Countersunk Hole Magnets with Mounting Screws - 60x13.5x5mm, Pack of 8

This may sound silly but my Depression Era kitchen had one of those old Kohler cast iron,enamel covered kitchen sinks with drainboard built in and it's slightly sloped so water can drain to sink. This means that my rubberclad wire drainboard slowly works its way to edge of the sink. I tried securing it to the wall with a cable clamp but then I gotta unscrew it to scrub the enamel drainboard. When I saw these I had a light bulb moment because they are crazy thin and crazy strong so I screwed 3 of them to the wall right at the drainboard rim and these magnets did the trick.....love it !!!

These are really nice magnets, very strong. I used them to hold greenhouse doors closed and they hold very well. The magnets are thin and come with the screws needed to mount them. They work well no problems at all.

Great to use with antennas

These magnets are super-strong and very versatile, however, I should have looked closer as a description to make sure it was a stainless steel channel the magnets are housed in. After a couple of months of being outside, the steel channels are starting to rust as you can see in my photos. If I would have known they would start rusting being outside, I may have chosen the black ones. Still, the magnets do work very well, hold a lot of weight for their size and are about 6cm L x 1 1/2 cm W. I like the fact these have countersunk holes which gives it a cleaner look and the screws don’t stick out if you’re going to use them in a cabinet or something.

Hell, they work very well. Their magnetism is very strong. I'm glad with them.

Fun to play with but is practical too. Holds freezer door shut so seal works. Replaces buoy magnet on security door sensors were space is a problem!

The bad: 1 of the 4 magnets was broken (cracked) when I opened the package this morning, so that is a non-starter for me. If not for this issue, I would keep these. The not so bad: Description specifies 80lbs of pulling force so I put it to the test with one of the good magnets. I could lift steel kettlebells of increasing weight up to and including 26lbs but nothing heavier. So from a pull force perspective of 80lbs, that’s about 32% of rated capacity. Don’t get me wrong, if you need these for small tools or cabinets, more than strong enough, but less than I was looking for.

Two of them will hold a full size Beretta 92 to the bottom of a table. Only issue is they will leave scratches if you move you items often and don't cover them with something.

Good strong magnets. Used for a project outside. No loss of power and they were easy to install.

These work well. They're good for organizing tools. I have both these as well as the disc magnets in my shop, and the disc magnets are stronger.

I wanted to make a "magnetic wand" to use to retrieve nails from the ashes of my wood stoves when I use cut up pieces of packing skids for fuel. Neodymium magnets are good for this application but they are usually hard to attach other than using adhesives and are notorious for shattering if impacted by hard objects. These magnets solve the attachment problem completely (just don't tighten the screws too much or the hard metal of the screws may crack the magnets) and the metal shroud gives significant protection against impact damage. So far very pleased with them. They do this job very well and much faster than my previous method. One further comment... I investigated getting these magnets direct from China via common Chinese online retailers. It turned out that the best price by a significant margin was here on Amazon. In addition, many of the offers by Chinese online retailers were deceptive. For example, they would show the same photo as used on Amazon of 8 magnets and the price was attractive, but in the fine print it was stated the offer was for only 2 magnets. You have to read the fine print carefully! Otherwise verndors will take advantage of you.

If I was screwing into wood these would be perfect, but I've been having a heck of a time making these work with drywall. Very strong, they definitely keep the cat out of the closet, but I've yet to figure out how to use them and not rip them out of the drywall.

Good as expected
