Uses for Countersunk Magnets

We have dozens of different countersunk magnets, in various shapes, sizes and strengths. These are some of our most popular magnets, but what can they be used for? In this article, we'll highlight some common uses for countersunk magnets and provide answers to commonly asked questions.

Basically, countersunk magnets are good for whenever you need to securely fasten a magnet to an object or surface. Gluing magnets works, but sometimes you need something more rigid, which is where countersunk magnets are great.
