I need a new bolt for my sink drain air filter, but what thread is it? I went to the hardware store today and of course got the wrong thread. Any help is appreciated.

This was another idea I had, it's a screen from a sea strainer from a boat I worked on a few years ago. Ill have to cut it at the green tape and top it off with a SS fender washer. I think I like the cheap Chinese sink drain though:doah:
