20pcs 12mm x 3mm (Approximately 1/2" x 1/8") Countersunk Ring Magnets

Rare Earth magnets are the strongest magnets in the world. These magnets have pull several times their weight.

You receive:

These incredible magnets are great for anything that you would use Velcro, brass fasteners, hinges, pins, etc. My clients range from craft companies to hobbyists to painters to carpenters to purse makers. These little magnets have MILLIONS of applications.

1/2" diameter is the heavier-door countersunk. Tool cabinet doors, large 3D printer enclosure panels, lift-off lids on prop boxes and ammo cans. 6.3lbs of pull holds a 3kg acrylic door without sag. The M3 countersunk hole takes a flat-head screw flush with the magnet face so it doesn't catch on the mating steel.

WARNING! These magnets should be kept away from any animal or human who might try and eat them, they have the potential to separate and pinch intestines causing serious and life threatening complications.

BRITTLE! These magnets are more brittle than glass, please make sure you don't let them slam into each other or drop onto the floor, they WILL break and I will be sad for you.

Let me know if you have any questions!
