Countersunk Magnets

Countersunk magnets are an extremely popular fixing method due to their ease of application, clean aesthetic and strong performance. These magnets are easily fixed in place with screws and are used for discreet door and drawer closures and for signage and displays.

What is Countersunk Magnet

Countersunk Magnets, also known as Round Base, Round Cup, Cup or RB magnets, are powerful mounting magnets, built with neodymium magnets in a steel cup with a 90° countersunk hole on the working surface to accommodate a standard flat-head screw.

advantage of the pot magnet is that it is recessed in the steel shell, which reduces potential impacts and therefore chipping.

What are countersunk magnets used for?

When the door is open, it will latch onto the floor’s magnet and stay put. You can also use magnetic latches for keeping kitchen cabinets or drawers closed, as well as with filing cabinets or lockers. Really, anything can be held open or closed with strong neodymium countersunk magnets!

How do you install countersunk magnets?

Installation is simple: Drive the screw through the hole in the countersunk magnet, drilling it flush with the top of the countersunk so there’s no chance of the magnet shifting or snagging anything nearby. Finally, be careful not to over-tighten the screw, especially when using an all-magnet countersunk

All the strength of pot magnets are the vertical magnetic pull-force which make the magnet pull away from the 20mm thickness steel plate of a tensile tester under ideal condition. (80mm/min)
