Default Self Sealing Hex Screws

Hey guys, I'm looking for a solution for grounding my heating element. I figure a stainless steel bold, some washers, and seals would work. But than I found these (http://www.mcmaster.com/#cap-screws/=7v4osb) McMaster-Carr self sealing screws. Anyone have any experience with these?

Is this being used on a kettle or keg? If its a keg just attach it to the skirt. I soldered an SS bolt to my keggle and fastened the wire connector to it.

An aluminum kettle.

You can always tap (thread) a hole drilled into the "hex Head" of the element and ground it there. I'm not sure if solder will work but I bet a google search would give you the answer. My guess is that it can be soldered.

That's an excellent idea, but I would guess a bigger pain than just drilling a hole in my kettle and throwing a screwing it.

Could you drill the hole at the top so you don't have to even seal it?

I just wouldn't trust a self-tapping screw to hold in that thin sidewall. Especially when it secures the ground. I say you through bolt it or tap the head.

Then you'd have to run a long ground wire from the bottom where the element is to the top, I don't like that idea. It would get snagged I'd think.

I believe that the ground wire needs to come in contact with liquid. Doesn't it?

Thus my wanting a bolt on the inside contacting with liquid and the wire contacting with the bolt.

But correct me if I'm wrong, that would make this a lot easier.

No, it doesn't...

Grounding the metal, either directly on the element, or on the pot (Which is electrically connected to the element) is all you need to do.

Everything is touching everything in an electric BK - You could wrap your ground around the handle and get a good ground - Not that I'd recommend that
