Yes quite difficult to find those 3/16 x 32. If you buy chaincase screws from most sellers now they will just give you 2BA as the nearest equivalent. I've used stainless 2BA in all my BSA's and bead blasted the heads for a cad plated look. Ron

What's the recommendation on grease ?

Pack the entire hub when stripped & a couple of squeezes from the grease pump to suffice
Or
Just pack the bearing area best you can
