The MIKEDE 15x3mm neodymium magnets are pretty strong and popular for various DIY projects and light-duty work. They are made from high-quality neodymium and come with a countersunk hole for screw mounting, which makes them easier to use.
But, there are a few things to watch out for. According to our research, some folks noticed an issue with the magnetic polarity. Apparently, the magnets often have the same polarization direction throughout the pack. This can be a problem if your project needs the magnets to attract each other, like when aligning panels or securing lids. Instead of attracting, they might repel if they're oriented the same way, making things a bit tricky.
Another thing is that they have a countersunk hole on only one side. So, if you mount them with the flat side against a surface, the screws might stick out a bit since the countersink doesn't go through to the other side. Depending on your project's needs, this might not matter. But if you need the screws to sit flush, you might have to get creative with washers or tweak the surface.
Overall, these magnets get good marks for strength and can handle a variety of tasks like hanging small items and crafting.
Just remember, if you need precise alignment or heavy-duty strength, there could be some limits. Knowing these quirks can help you get the best out of them for your projects.
