Increasing values for higher steel tensile strength per Note 6 is not allowed. <br />3For tension connections, the lowest of the available pull-out, pull-over, and screw tension strength must be used for design. <br />4Values are based on steel members with a minimum yield strength of Fy = 33 ksi and a minimum tensile strength of Fu = 45 ksi. <br />5Available capacity for other member thickness may be determined by interpolating within the table. <br />6For steel with a minimum tensile strength Fu ≥ 58 ksi, multiply tabulated values by 1.29 and for steel with a minimum tensile strength Fu ≥ 65 ksi steel, multiply tabulated <br />values by 1.44. <br />7Head styles: HWH = Hex Washer Head; PPH = Phillips Pan Head; PWH = Phillips Wafer Head; PUFH = Phillips Undercut Flat Head. <br /> <br /> <br />13
