Collection: Countersunk Ring Super Magnets

A countersunk ring magnet has a tapered center hole, so you can fasten it down with a flat-head screw and have the screw sit flush with the surface. That gives you a mechanical hold and a magnetic one, which matters for mounting points that take repeated stress or need to stay put permanently.

These come in 6mm, 8mm, 10mm, 12mm, and 20mm diameters, all 3mm thick. They suit panel mounts, tool holders, removable hatches, jigs, and any build where a glued-in magnet would eventually work loose.

We recommend matching the screw size to the countersink; if you are unsure, the larger diameters take a standard countersunk wood or machine screw.
