Got our screw supplier to subsidize a test program roughly following ICC-ES AC120-05' sec 4.2 and ASTM F1575. The stainless steel type A SMS had 79 to 83% of the presumptive bending yield strengths of carbon steel wood screws listed in AFPA-NDS-2001'. Also tested some hardened carbon steel...
AFPA-National Design Sec for Wood Construction 2001 has lateral design equations for screws in wood that use fastener bending yield strength. But NDS only references typical bending yield strengths for carbon steel. We use lots of #8 thru #12 screws of 304 stainless steel.

1.) Can EOR challenge the Bldg Official(s)? Yes
2.) Say a house is in middle of development and has initial C exposure to north. When development is completed then B exposure in all directions. If there is a "reasonable degree of certainty" (as the deposing attorney will say) that the...
NDS 2001 has lateral design equations for screws in wood that use fastener bending yield strength. But NDS only references typical bending yield strengths for carbon steel. We use lots of #8 thru #12 screws of 304 stainless steel.
