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).

1. Allowable (ASD) capacities are based on a safety factor,  = 3.00 in accordance with AC491.
2. Allowable (ASD) capacities are based on 6061-T6 aluminum members with a minimum tensile strength of F
u
= 42 ksi and a minimum yield strength of F
y
= 35 ksi.
3. Allowable (ASD) pull-out capacities for other member thicknesses may be determined by interpolating within the table.
4. For aluminum with a minimum tensile strength F
u
≥ 45 ksi and a minimum yield strength of F
y
= 40 ksi, multiply tabulated values by 1.14.
5. 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.
