What thread/size bolt is correct for this? Thanks.
Pete, the R&O says 3/8 - 27tpi. I checked mine and indeed that's what's in there!
Thank you.
Pete, off the top of my head, 1/8 npt, which is a tapered pipe thread. Don't use a brass plug that is available from hardware stores, they can get frozen in.
