Tabulated lateral design values,Z,are for"reduced body diameter lag screws(see Appendix Table L2)inserted in side grain with screw axis perpendicular to wood fibers;screw penetration,p,into the main member equal to 8D;dowel bearing strengths,F„of 61,850 psi for ASTM A653,Grade 33 steel and 87,000 psi for ASTM A36 steel and screw bending yield strengths,F,h,of 70,000 psi for D=1/4",60,000 psi for D=5/16",and 45,000 psi for D>3/8". 3, Where the lag screw penetration,p,is less than 8D but not less than 4D.tabulated lateral design values,Z,shall be multiplied by p/8D or lateral design values shall be calculated using the provisions of 12.3 for the reduced penetration. 4. The length of lag screw penetration,p,not including the length of the tapered tip,E(see Appendix Table L2),of the lag screw into the main member shall not be less than 4D. See 12.1.4.6 for minimum length of penetration.p P L-r 2- AMERICAN WOOD COUNCIL
