'The lower of the allowable shear (bearing) and the allowable fastener shear strength found in Tables 4 and 5, respectively, must be used for design. 2ANSI/ASME standard screw diameters were used in the calculations and are listed in the tables. 'The allowable bearing capacity for other member thickness can be determined by interpolating within the table. 4To calculate LRFD values, multiply values in table by the ASD safety factor of 3.0 and multiply again with the LRFD (V factor of 0.5. 'For Fu = 58 ksi, multiply values by 1.29; for Fu = 65 ksi, multiply values by 1.44. TABLE 5-FASTENER STRENGTH OF SCREWS' 2, 3, 4, 5 SCREW DESIGNATION DIAMETER (in.)
