1. All applications are based on full penetration into the main member. Full
penetration is the screw length minus the side member thickness
2. Allowable loads are shown at the wood load duration factor of C
D
=1.0. Loads
may be increased for load duration per the building code up to a C
D
=1.6.
Tabulated values must be multiplied by all applicable adjustment factors per
the NDS.
3. For in-service moisture content greater than 19% : withdrawal C
M
=0.65;
shear C
M
=0.68.
4. For multiple fasteners, minimum fastener spacing requirements: 8" end
distance, 1
½ " edge distance,  " between staggered rows of fasteners, 4"
between non-staggered rows of fasteners and 8" between fasteners in a row,
multiply the table values by 0.80.
5. Tabulated loads are for both parallel and perpendicular to grain loading.
6. Maximum withdrawal loads are based on the length of threads in the
main member.
