Let me know (via the newfangled private message feature) if this link stops working.
If you prefer a "printed" copy, the current Simpson catalogs don't have these tables, but the offsite copy of the 2013-2014 Simpson Wood Construction Connectors Catalog has it. [ School of Professional Home Inspection web site ].
ETA: 12/23/24 - I don't have a 2010 Catalog, but the 2009 Catalog doesn't have these tables, and the 2011 does. Simpson did an annual catalog for a fair while. 2012 was maybe the last annual catalog, now it's every 2 years.
