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

These were much stronger than expected. They worked great in my workshop. Easy to mount.

quand on vise l'aimant alors la pression le fait se cassser

These things rock. I use them to hang framed pictures in my pole barn. Two of them will hold a 14x14 full framed glass picture frame. The larger pictures are 36x42 four holds those no problem. Very strong

I had read a lot of reviewers saying the magnets break easily. I didn't break any magnets but the brackets housing the magnets broke quite easily when I screwed them on. I left the magnet with the cracked bracket installed and after a couple of months it still works good. I am using the magnet to hold the door to my chicken coop open while I am in and out of there tending my livestock. ( I keep all my feed in the coop). I got tired of the door being slammed into me by the wind. Problem solved.

Very strong and great for many projects!
