This allows you to pair them together to create magnetic latches, fasteners, and other closure mechanisms. Both the north and south poles will be attracted and attach to anything metal.

If you need the magnets in a different configuration, please contact us.


Drill Torque Information
It is very easy to overtighten and break/crack countersunk neodymium magnets when screwing them in place. We recommend hand tightening when possible. If using a drill, start with a low torque setting and work your way up.


Black Epoxy Coating

Epoxy coated magnets are commonly used in industrial and commercial applications due to their exceptional corrosion and chemical resistance, making them ideal for outdoor or marine enviroments.

Perfect size

Used these magnets on the lid of my toolbox to attach small tools. Very easy to bolt on, and just the right amount of grip to hold hex wrenches.

The magnets are SO cool!

I bought them to make a moveable sculptures parts tend to stay in place. Have not got that far yet, but they are amazing to play with. The repulsion of same poles is incredible; feels like a living thing.
