Master MagneticsCeramic Round Base Magnet Pack with Hole, Ideal for Securing Items in Home, Shop, and Commercial Spaces, Multiple Sizes

These magnets are very strong and very well made.They worked great for mounting a power strip on the side of my rolling too cabinet

One of the most powerful magnets for lay use I’ve found! The hole allows for affixing bolts, bolt-eyes, etc. For my purposes that wouldn’t work, however a little Gorilla Glue and it’s held on to a solar motion light in all kinds of weather, without ever separating the magnetic hold!

Powerful

Hold well. I use them to hang signs on the wall in my garage.

But it appears that the shielding part is made of stainless steel which does not conduct a magnetic field very well. The only reason this matters is in the way I use these. I've tied them to winter golf tees, rubber tees with various heights. If the shiny side is up there is very little magnetic pull, needs to be flipped over to pick the tees up. I'm well into my 70's and need every convenience I can find! Other than that these are well made. I think I'll heat one up and see if I can break the glue bond holding the two pieces together.

Worked perfectly for the application I needed them for

I used two of these to attach a light bar to a JD 1025R ROPS. They're pretty good magnets and hold the bar in place decently well (when shaken REALLY hard, it fell off once). I'm quite happy with the magnets though.

These magnetic are incredibly well magnetic. If you’re not careful you will like me pinch your finger between them but saying that I’m sure I can hang off of them with ease. Honestly I bought these to put on my powerblock dumbells to add a smaller amount of weight per jump. Each one weight 1.5 pounds so it was perfect for that.
