MIN CI Strong Neodymium Disc Magnets with Holes, 20 Pcs Heavy Duty Countersunk Magnets with Screw, Small Ring Rare Earth Metal Magnets Hole in Center for Wall Mounting 0.7" Dx0.12 H

I just friction fitted these into one of my dowel racks, they’re strong enough to hold my combination squares, steel hole punches, and both of my Suizan flush cut Japanese pull saws. I tried hanging a full size hammer from one but it’s not quite strong enough for that, but i would think one of the bigger size magnets could hold it. These were my first purchase of Neodymium magnets and they didn’t disappoint.

good, strong magnets.

Out of 30, 3 shattered. So not bad. They are brittle, not once you discover the breaking point, just don't go there again.

Very strong magnets and with the countersink hole the can be mounted to almost anything.

One of the magnets arrived broken, the polarity of about 40% of these was different than the rest so i could not use them for what i intended to.

These magnets are extremely strong for their size, the screw hole in the center allows for easy installation.

Items worked perfect and a great price

When you try to screw these in tight, they break in half. Even using a hand screwdriver, they are extremely easy to snap. The alternative is leaving them loose so they spin, which is not a great option.

Very good and magnets are strong

small but strong
