Im in school learning industrial wiring, and dc motor controls... I also brew beer at home and have been planning on building an electric brewing set up which includes a panel and numerous switches and pushbuttons.
Since people strip out the screws and terminals in the pushbuttons, my teacher gives them to me to try and fix to use in my brewing adventures. I have about 10 right now and I took one apart and all it needs is the terminal that the screw threads into.

Does anyone know if I can order some to replace them with? I figure if I can repair them, it'll be worth it as each switch is 20-30 bucks.

Easy, find out what the thread pitch is and purchase a tap and die.

If you can find a nut with the same threads
you can solder it on the bottom side.

6 in 1 Klein tap. Just one size larger, like a 10/32.

I'll get a tap this weekend and some new screws for the pushbuttons. Thanks for the tips everyone!

I recieved 3 motor coils from school because the screws are stripped out... Ive added some pictures and am hoping people have some ideas of if I can get new terminal screws with the little square plates on them.... Hopefully i can get the bad screws replaced and use the coils to control some pumps in my brewing setup.
I also need new heaters for the coil in the last picture.

Nobody sells those screws, not retail anyway and to buy them from one of the few suppliers that service the motor control mfrs, you'd have to buy 10,000 at a whack. There's usually nothing wrong with the screws (unless the head slots get twisted out), because they are harder than the brass parts they screw into.

None of these things are designed to be repaired, so nobody sells parts for them. Your best bet is to find lots of them and scavenge good parts on some to fix bad parts on others, since you seem to have the time and not the money... The working among us don't have time for that stuff, we rip and replace, it costs a lot less.
