• Wood Screw bending yield strength of 70000 psi is assumed.
• Dowel bearing strengths for wood screws with nominal diameter greater than 1/4 in.
are calculated and rounded to the nearest 50 psi in accordance with NDS Table
11.3.2.
• Length of tapered tip is assumed to be two times the nominal wood screw diameter
for calculating dowel bearing length in the main member.
• ASTM A36 Steel is assumed for steel side members 1/4 in. thick, and ASTM A653
Grade 33 Steel is assumed for steel side members less than 1/4 in. thick.

• The Adjusted ASD Capacity does not apply for wood screws installed in the end
grain of wood members.
• The Adjusted ASD Capacity only applies to withdrawal of the fastener from the
main member. It does not address head pull -through capacity of the fastener in the
side member.
