Dear S-
If your house is a block away from an active fault & it let's go, I
really doubt that a heavier joist hanger is going to make a difference.
I like the HU series...none of those silly cutouts just nice uniform
edges
I'm not a huge fan of large nails....in my experience 16d commons are
too large for nearly all commonly used residential timbers.
At .162" diameter & not pre-dillled, 16d commons (IMO) do more harm
than good.
Who pre-drills for joist hangers? Even though there is a buried note
(note J) in the Simpson catalog that comments on nails that split
the wood & suggests considering pre-drilling
IMO the best compromise is the 10d common (.148) or any of the reduced
size 16d's
Bigger ain't always better if you don't pre-dill. In most SImpson
connectors the nails are so closely spaced that you're bound to get a
lot of wood damage esp with the larger nails.
Use the 10d's & be happy.
cheers
Bob
