yesinductane heating stainless steel bolts
For heating a thick steel bolt to red glow, you can't use a wire for the inductor coil. It has to be copper tubing, and you have to run plenty of cooling water through it. Otherwise the coil tube is going to melt through before your bolt is red.

Also, 50/60 Hz will get you nowhere. At least a few kHz are needed, and the inverter should be in the 10kW power range for that bolt you describe.

You can certainly build something like this yourself but it makes no sense to do that for one single bolt.
