1. Ultimate strengths are based on laboratory tests.

2. Allowable (ASD) strengths are based on a safety factor, , of 3.00 in accordance with ICC-ES AC491 and AISI S100-16.

3. Design (LRFD) strengths are based on a resistance factor,

, of 0.50 in accordance with ICC-ES AC491 and AISI S100-16.

4. For ASD tension connections, the lower of the ASD tension strength, ASD pull-out strength and ASD pull-over strength must be used for design.

5. For LRFD tension connections, the lower of the LRFD tension strength, LRFD pull-out strength and LRFD pull-over strength must be used for design.

6. For ASD shear connections, the lower of the ASD Shear (Bearing) Capacity and the ASD Fastener Shear Strength must be used for design.

7. For LRFD shear connections, the lower of the LRFD Shear (Bearing) Capacity and the LRFD Fastener Shear Strength must be used for design.

1. Unless otherwise noted, ultimate strengths are based on calculations in accordance with the Aluminum Design Manual, AA ADM1-2015.

2. Ultimate strengths are based on laboratory testing.

3. 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).

1. Allowable (ASD) strengths are based on a safety factor , =3.0, determined in accordance with the Aluminum Design Manual, AA ADM1-2015.

2. Values are based on aluminum members with the following minimum tensile strengths: 6063-T5, F

= 22 ksi; 6063-T6, F

= 30 ksi; 6061-T6, F

= 42 ksi

3. The first number is the thickness of aluminum in contact with the screw head, the second number is the thickness of the aluminum not in contact with the screw head.

4. Allowable (ASD) Shear (Bearing) capacities for other member thicknesses may be determined by interpolating within the table.

5. For aluminum with the following tensile strengths: 6063-T5, F

= 27 ksi; 6063-T6, F

= 35 ksi; 6061-T6, F

= 45 ksi; multiply tabulated values by 1.22, 1.16, 1.07 respectively.

6. For ASD shear connections, the lower of the ASD Shear (Bearing) Capacity and the ASD Fastener Shear Strength must be used for design.
