That is why I said Helicoil. That is an automotive item. It makes new threads in metal without retapping once you get it out lickity split. Unless you just use a self tapping stinger screw but I vastly prefer the former with a proper machine screw. Being such a cheap board it does not matter much I guess. It is not surprising at all it got hit with two screws. Built by robots. This happens to all kinds of things more often than you would think. The robot screw gun station misfires too quickly in succession. At least this is right out in the open and not a royal R&R job. Like losing a tiny screw down the carb barrel into the intake all the way into the head! Trust me, I have done that trick oops. Now I would remove the entire carb and not risk that anymore. Well I guess this might be one reason to buy a keyboard kit, no? I have actually probably drilled out tens of screw heads in my time. There is a bit just for that. Right bit makes the job easy and not mess up the item. Look for it at Menards. It is cheap. Helicoil is not cheap so probably not worth it here.
That's all very interesting. I hadn't thought about automation, that makes it make more sense. I seriously imagined the previous owner, since this was apparently used, somehow screwing a screw straight into the head of another screw, which must not be humanly possible. I'll have to look into those helicoils. They look interesting.
I don't think that Menards reaches out even into the entirety of the midwest, although I do hear it is spreading from people I know online that are a few states away. We're kind of spoiled in that we've got both Fleet Farm and Menards.
