1. Allowable (ASD) strengths are based on a safety factor ,, determined in accordance with AISI S100-16.
2. Values are based on steel members with with a minimum tensile strength of Fu = 45 ksi.
3. Allowable (ASD) Shear (Bearing) capacities for other member thicknesses may be determined by interpolating within the table.
4. For ASD shear connections, the lower of the ASD Shear (Bearing) Capacity and the ASD Fastener Shear Strength must be used for design.
5. Unless otherwise noted, for 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 values by 1.44.
6. The first number is the thickness of steel in contact with the screw head, the second number is the thickness of the steel not in contact with the screw head.
7. For steel with a minimum tensile strength Fu ≥ 55 ksi, multiply tabulated values by 1.22.
8. For steel with a minimum tensile strength Fu ≥ 52 ksi, multiply tabulated values by 1.15.
9. For steel with a minimum tensile strength Fu ≥ 58 ksi, multiply tabulated values by 1.29.
10. Increasing values for higher steel tensile strength per Note 5 is not allowed.

1. Design (LRFD) strengths are based on a safety factor , f , determined in accordance with AISI S100-16.
2. Values are based on steel members with a minimum tensile strength of Fu = 45 ksi.
3. Design (LRFD) Shear (Bearing) capacities for other member thicknesses may be determined by interpolating within the table.
4. For LRFD shear connections, the lower of the LRFD Shear (Bearing) Capacity and the LRFD Fastener Shear Strength must be used for design.
5. Unless otherwise noted, for 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 values by 1.44.
6. The fisrt number is the thickness of steel in contact with the screw head, the second number is the thickness of the steel not in contact with the screw head.
7. For steel with a minimum tensile strength Fu ≥ 55 ksi, multiply tabulated values by 1.22.
8. For steel with a minimum tensile strength Fu ≥ 52 ksi, multiply tabulated values by 1.15.
9. For steel with a minimum tensile strength Fu ≥ 58 ksi, multiply tabulated values by 1.29.

1. Ultimate strengths are based on laboratory tests.
2. Ultimate load capacities must be reduced by a minimum safety factor to determine allowable loads (ASD) or by a load resistance factor to determine strength design capacities (LRFD).
