Fastener length exceeds total connection thickness
• Wood Screw bending yield strength of 80000 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.
While every effort has been made to insure the accuracy of the information presented,and special effort has been made to assure that the
information reflects the state-of-the-art,neither the American Forest&Paper Association nor its members assume any responsibility for any
particular design prepared from this on-line Connection Calculator.Those using this on-line Connection Calculator assume alt liability from its use.
The Connection Calculator was designed and created by Cameron Knudson,Michael Dodson and David Pollock at Washington State University.
Support for development of the Connection Calculator was provided by AF&PA's American Wood Council.
