I just measured one of mine - it was 0.16 inches, the hole on the
layout looks to be a couple of hundreths smaller than that. The part
also has some sealant material at the base of the nipple which makes
it a little larger - approx 0.18 inches.
You seem to have the room, so I'd make it bigger - which would also
help if the pins were slightly bent or misaligned.

such a large space around the nipple hole is so that i can enlarge it
later, as I do with the B7971 pcb's.
thge board house I used last and will probably use this time wanted
more money for the extra large drillings so I just mark the point
with a 3mm hole and expand it later for myself. The datasheet
specifies a maximum of 8.5mm and that looks like it will fit well
I'll take your and David's comments as confirmation that at first
glance all seems well enough to go ahead and order a batch. I'll keep
you posted as things progress.
