Master Magnetics Ceramic Round Base Magnet with Knob Pack - Heavy-Duty Strong Magnets with Knobs for Home and Work - 16 lb Pull Each - Nickel-Plated - 1.43" D - 0.98" H - Chrome - 4-Pack

I love that these are super strong and hold a lot of weight without budging. I bought them because I wanted to add a pull handle to my metal workshop cabinet. I didn't want to drill a hole in it because I inherited it from my dad. It looks great - like it's always been there (see pics). Since I had a set of them, I discovered that they were even better for hanging my hacksaws and miter saw than the magnet hooks that I had been using. The round knob holds them more securely. This was a great find!

Great mutli-purpose magnets that work great

These are strong magnets! They'll hold up quite a bit of weight. They're not so strong that you can't remove them. We wind paracord around them and use them outdoors. Over time, I'm sure they'll rust, but for now they've held up well in dry weather...

Advantages:(1)These very strong magnets will easily hold a heavy calendar on an iron-alloy wall.(2)The parts of this product that people would normally look at are attractive.Disadvantages:(1)The biggest disadvantage is that the neodymium magnet underneath is not nickel-plated and so it looks black and ugly.(2)The magnet underneath has a bolt in the center, which cannot be loosened and should not be loosened.(3)On approximately 2 of the 4 magnets, just underneath the top of the black plastic knob, there will be black plastic debris which the buyer might very likely want to remove. A Revlon Cuticle Cutter will not be able to get into the correct angle to clip it off. A long nose pliers or tiny scissors could be used. However, I've found that simply moving my index finger back and forth for about 30 to 60 seconds is the best way to crack away this 1 hanging, unwanted debris.Discussion:(1)The diameter of this product is 1-3/8" and the height of this product is 7/8".(2)Other magnetic products that can be used to hang a heavy calendar on an iron-alloy wall include any eyebolt magnet and also the Learning Resources brand "Super Strong Magnetic Clips," which are sold as a set of 4 colors. Plastic clips with tiny neodymium magnets attached to them tend not to be strong enough to hold a heavy calendar on an iron-alloy wall unless the plastic clips are glued to the wall; their plastic jaws would be strong enough to hold the heavy calendar.

The motion sensor broke on my trash can so I bought these to use as a knob for opening the lid. Works great! Would buy again if needed.

I originally purchased this little magnet as a handle for aluminum roasting pans. A washer inside the pan and this little magnet on the top makes for a very affordable food cover, of any size. Since then I've used the magnets to hold a vinyl cover in place against the wind on a prep table. They also work well to mount documents, etc on metal cabinets.

These are way smaller in person than I thought. They do seem sturdy and the lid locking mechanisms are strong! We will see how the glass holds up

They fit! Great idea to have extras as they are misplaced often.
