Got them quickly. Nice!

If you have a micro controller in one hand and a PCB in the other, you might be tempted to solder the controller to the board. Well you could alternatively solder a socket to the PCB and then use these little fellas to make it possible to remove the controller without the tedium of removing solder.

Good little pins, what else is there to say

One of the controllers on my keyboard got fried. Having a socketed controller made swapping out the damaged one for a functional one a breeze!

Gives a much better contact in the sockets than using diode legs. Much tidier looking as well.

Well worth the pennies.

Beware, just ferrous enough, to be stuck to a neodymium magnet for a split second before most of them get catapulted through the room because you brought something metallic too close to it. Cheap enough to consider ordering more than you need, and they make the actual building process much cleaner and easier.
