Extend the threading

[Mc Doc]

Hi lads, I need help with my small brewery.

I need to extend the threading on the two screws. They are standard plumbing screws. Who can be able to extend the thread on them?

I need extend as much as possible.

If it possible,  I would like to know how much it would cost (you can use PM).

Thanks

Talk to dempsey, I think he has a metal guy.

Why do you need them extended what are you trying to do?

It is a quick connection (hose connection) for recirculating wort. I can show late.
