Applications:

These high-quality, strong countersunk ring magnets are specifically sized to fit #4 flat-head screws. Sold in pairs, each magnet is precisely designed with one having the north pole on the side of the large end of the hole and the other with the south pole on that side. This polarity ensures they attract each other when screwed in, making them ideal for secure fastening applications.

Perfect for a wide range of uses, these magnets are commonly used in door closures and tool hangers, as well as other innovative projects where strong magnetic attraction is needed. Their countersunk design ensures a flush and secure fit when used with flat-head screws.
