from end grain, reference withdrawal design values, W,
11.2.1.1 The reference withdrawal design values, in shall be multiplied by the end grain factor, C.g = 0.75.
Ib/in. of penetration, for a single lag screw inserted in 11.2.1.3 When lag screws are loaded in withdrawal,
side grain, with the lag screw axis perpendicular to the the tensile strength of the lag screw at the net (root)
wood fibers, shall be determined from Table 11.2A or section shall not be exceeded (see 10.2.3).
Equation 11.2-1, within the range of specific gravities
and screw diameters given in Table 112A. Reference
withdrawal design values, W, shall be multiplied by all
