Subject: Simpson 3x3 washers for sill plate anchors

2305.3.11 of the 2007 CBC requires 3x3x.229" thick washers. Oddly Simpson does not make this for a 3/4" anchor bolt. They do make a 2.75x2.75x5/16" for 3/4 anchors, but this does not meet the code requirements. They do make a 3"x3"x1/4 for 1/2" and 5/8" dia anchors. So if we want to use 3/4" anchor bolts the washers need to be fabricated unless someone else makes these.
