Are 2 X 2 X 1/4 washers required?? Using the 2003 IRC. They are still using the small round washers here in southwest Kansas. They are also drilling one inch holes for 1/2 anchor bolts. For me they should use those square washers just on that fact alone.
 
Re: washers

sorry not familiar with s.w. kansas. what seismic design catagory? also can't find it right now in the 03,( might be a reference standard), but there is a max. size for bored holes over the size of bolt.
 
Re: washers

2003 IRC requires 3x3X1/4 plate washers in seismic D1, D2, and townhouses in C. Otherwise 1/2 x 7 bolts with plain washer. 2003 IBC requires 2x2x3/16 plate washers in seismic D, E, or F. 2006 IBC and IRC require 3x3x1/4 in the same respective seismic design categories. I don't know of a code section for maximum bore diameter.
 
Re: washers

JayHawk,

Square washers? Do you mean the foundation wall spreader tabs that are removed from the foundation wall after the wall is striped?
 
Re: washers

Globe Trekker,

Have'nt seen those in this area at all, amazing :shock:

I might see them on a future commercial job but doubt I will see them on any residential here, unless the the big box has them!
