These are very strong magnets.Be careful what you stick them to as you may have a ridiculously hard time removing them.I use these for so many things, I can't hardly begin...but they're awesome to have in any shop.Just for fun, if you wish for a little extra entertainment during your day, drop one of these in your pocket and forget about it. (you won't be able to for long)

As an avid laser engraver, I needed something to keep my product in place, I use a sheet of galvanized steel to place my pieces on, but I need them to stay where they are so I use the small magnets to surround the piece and start the process, I think because they are such strong little magnets I can actually do more than just one piece at a time, leaving the magnets where they are I can just put the next piece down in place as it would be if it were a jig and running anywhere from 2 to 4 pieces at a time.They are extremely strong little magnets, I don’t think the screws would be useful in my case, but the magnets themselves are absolutely fantastic.I find them to be extremely useful and would recommend them to anyone.

I'm sure that, in order to make these magnets as strong as they possibly can be, the metal has to be brittle. Just be forewarned. They can shatter simply snapping them together. Be Careful!

These little magnets are powerful

I used these to hold metal speaker grilles to the cabinets on some garage speakers I built. The magnet being held in a cup is a good feature, making the assembly stronger. These magnets can be brittle, and the steel cup supports the magnet when screwed in place.The extruded steel grilles are actually fairly heavy, and these magnets hold them very firmly in place, even as the speaker vibrates at high volumes.

Good strong magnets! Perfect for any craft or project.

Magnet seems strong enough, but they can’t be screwed down with the screws included.

Very strong magnet
