Countersunk Neodymium Magnets
Neodymium Countersunk Magnets are a popular type of neodymium disc/block magnet that has a countersunk hole to fit a screw perfectly.
Magnets with countersunk mounting holes allow them to be screwed into place with the screw head flush, making them ideal for any engineering, manufacturing or DIY task.

Are Countersunk Magnets available in different shapes?
Countersunk magnets come in all shapes and sizes depending on the requirements. The most common shape is disc and block magnets, however, they can be cylindrical or spherical. They can also be completely customised to neatly fit inside of an intricate design. We can customise these magnets to your exact specifications of size, shape, strength and coating (minimum order quantities may apply).
Are they magnetic on both sides?
We often get asked whether the countersunk ring magnets are magnetic on the countersunk face, the answer is yes magnets are magnetic on both sides.
What is the difference between countersunk magnets and pot magnets?
Countersunk magnets and pot magnets are similar due to them both having holes that allow for screws. However, unlike ordinary countersunk magnets, pot magnets have a steel shell that covers the flat side of the magnet. The shell provides a protective barrier that partially protects the magnet from damage and corrosion, however, it is not magnetic on the back.
Will the magnets come in pairs?
When you purchase countersunk magnets, they all come with the same polarity which means two countersunk facing magnets will repel each other. If you are wanting to use these as a locking mechanism, two Neodymium magnets magnetised together would require too much force to separate. These magnets are very strong and we recommend using steel washers to magnetise to instead.
Uses of Countersunk Neodymium Magnets
Neodymium is a rare earth magnet and these magnets are the strongest in the world. They are comprised of Neodymium, iron and boron and they generate a powerful magnetic field like no other. The attributes of Neodymium magnets give you an almost endless list of practical uses. Rare earth countersunk Neodymium magnets, or countersunk ring magnets, are specially designed to be drilled or fixed into place. Countersunk screw magnets come in various shapes such disc magnets, block magnets and pot magnets. All of these shapes have a countersunk hole that fits a screw head flush. Read on to learn more.
Shock Absorbers: As you know, magnets both attract and repel each other. Neodymium Magnets are often used as shock absorbers by using the magnetic repelling force to push against another magnet. This is due to the force generated by opposing poles on the magnetic face. To do this, you will need the two magnets poles facing the same way and they repel. The larger the magnet you use, the stronger the repelling force.
Magnetic shock absorbers have practical uses in engineering but many people use shock absorbers in their homes too. Homeowners have found magnetic shock absorbers to be really useful at stopping doors and fences from bashing into the wall.
Magnetic Tool Holders: Neodymium Countersunk disc, block and pot magnets are widely used all over the world to help store tools and equipment. The magnets have countersunk mounting holes that are often drilled and screwed into the wooden wall. When these magnets secured into place, they provide enough force to hang small hand tools like hammers, spanners and wrenches. Please remember, most stainless steel actually isn’t ferrous so magnets won’t attract to these.
Magnetic Cabinet Door Catches: Neodymium magnets can be small and still generate lots of power. This makes them perfect for creating magnetic door catches in kitchen, office, home and bathroom furniture. Using Neodymium countersunk magnets as door closures are really useful as they prevent hinges from overextending that usually leads to damage.
Sewing Countersunk Magnets: Neodymium Magnets are used all over the world in sewing textile, garments and fashion accessories. Since Neodymium magnets are so small, yet so powerful, they are perfect for creating magnetic latches on clothes, bags and purses. Moreso, many people actually sew magnets into curtains or blinds to fix them into place.
Hanging Picture Frames and Artwork: Countersunk Neodymium Magnets are often used to hold picture frames and artwork on the wall. It’s important to remember that it’s much easier to separate two magnets by sliding them apart. In fact, separating magnets by sliding them requires 33% less force than pulling them apart. It’s important to test the pulling strength of the magnet before attempting to hang anything on the wall.
Display Banners: If you’ve ever hosted an event, you’re probably familiar with the magnetic display banners. Roller banners are really popular because they are very easy to store. When they’re being used, the powerful integrated Neodymium magnets discreetly secure the banner into place.
POS and Retail Displays: Neodymium Countersunk Magnets are often used by small and large retail shops alike. Securing the magnets gives you a foundation that allows you to change display banners when you feel necessary. The magnets are small enough to be unnoticed, yet strong enough to firmly secure them into place. Many shop owners also use countersunk Neodymium magnets to secure their window displays to capture the attention of those passing by.
Re-magnetising Fridge Magnets: Fridge magnets are found in almost every modern home in the world. Sadly, they can lose magnetism after several years but there is a way to re-magnetise them with Neodymium countersunk magnets. All you’ll need is a 4-inch stainless steel threaded bar, two stainless steel hex nuts and strong Neodymium ring magnets.
- Screw the first hex nut to the bottom of the threaded bar – this will secure the magnets in place. Secondly, feed the threaded bar through the hole in the countersunk magnet.
- Thread the bar through another magnet, but this time it must be the opposite way around so the magnets repel. Repeat this process and you’ll have a bunch of magnets that are repelling each other.
- Get the second hex nut and screw as tight as you can until the magnets are touching.
- Once this is done, simply roll the Neodymium magnets over the back of your fridge magnet in a straight line. This will realign the magnetism and re-magnetise your fridge magnet.
Woodworking & Joinery: Neodymium Magnets are often used by woodworkers and joiners due to their discreet size yet incredible power they generate. This means countersunk magnets can be drilled into place and easily hidden or covered by textile, veneer or leather.
