Reference withdrawal design values, W, shall be multiplied by all applicable adjustment factors (see Table 10.3.1) to ob- tain adjusted withdrawal design values, W. W=18000''V" G-3 11.2.1.2 When lag screws are loaded in withdrawal from end grain, reference withdrawal design values, W, shall be multiplied by the end grain factor, C.s = 0.75. 11.2.1.3 When lag screws are loaded in withdrawal, the tensile strength of the lag screw at the net (root) section shall not be exceeded (see 10.2.3). Table 11.2A Lag Screw Reference Withdrawal Design Values (W)' Tabulated withdrawal design values (R) are in pounds per inch of thread penetration into side grain of main member. _...1. ..r.l..... .... .....q.... :.. —.1........,h— A.n o.r thu.
