Customer Reviews

Rare Earth 1/2 in. x 1/7 in. x 1/8 in. S Countersunk Ring Magnet (12-Pack) is rated 4.7 out of 5 by 3.
Rated 4 out of 5 by from For the magnets to work at their best, I find... For the magnets to work at their best, I find they must have a flat top or the mating component can wobble off. While a screw solves the problem of securing the magnet ( epoxy can be hit or miss when the magnets get pretty strong), the holes on these magnets didn't let appropriate-sized screws get low enough and I had to sand down their heads to make the assembly flat enough on top. The magnets are good and strong, though, so I give them 4 stars.

Rated 5 out of 5 by from Strong These Little things are super strong. I have used one to hang tools on. They are more expensive than the other magnet but wroth the cost.
