Default plugging EGT bung on Header?

I need to take the gauges out of my car and either swap a header with someone or plug the EGT hole I tapped on the header. Could I just simply put a bolt in it? The header gets close to 1500 degrees so I dont want a bolt melting or breaking off and going right through the turbo. Is there any other alternatives or is the bolt okay?

I have a bolt plugging my uppipe for that last 10k miles or so and no sign of breakage, IMO it'll be just fine.

Check your thread size first! Not sure what you have, but several EGT probes were using 1/8" NPT thread. You can get cheap brass pipe plugs at your local home supply for a couple of bucks and it should work, but I'd personally reccomend stainless as others have mentioned. If it's a normal bolt thread, find a good ACE hardware and grab a stainless bolt or socket cap screw. Not 100% sure where the best place to get stainless pipe plugs would be but summit has them for too much money:

And this place seems to sell them on the cheap:

Most EGT bungs are 1/8-27 npt. Go to Lowes or mcmaster.com and get a 1/8 male-female and a 1/8 plug. They are called brass pipe fittings on mcmaster.com.
