NOTES:
1.Values for 25 and 22 gauge are based on ultimate values divided by a safety factor of three.Values for 20 through 12 gauge based on
lesser of the ultimate value divided by a safety factor of 3 and the allowable bearing capacity per AISI Para. E3.3 for single shear and
no washer. Pa = Fp•dia.'thickness/2.22 . Fu = 45 ksi for 25, 22, 20 and 18 gauges and Fu = 65 ksi for 16, 14 and 12 gauges.
2. Values with asterik(') indicates bearing capacity governs. Those with N/A indicate screw is not typically used with that gauge thickness.
3. Suggested minimum of 0.50" edge margin and spacing for #6, #8 , #10 and #12 screws. Distances based on AISI paragraph E3.1 .
4. Engineer should confirm screws ultimate failure data and the appropriate factor of safety for a particular loading condition.
5. When joining materials of different gauges the value for the thinner material shall be used.

NOTES:
1. Values may be increased by 1.33 for wind or seismic.
2. When joining materials of different gauges the value for the thinner material shall be used.
3. Values are based upon Fu,the ultimate tensile strength of the material, with the allowable load = 0.75(t)(Fu)/2.5 per
AISI Section E2.
4. Fy = 33 ksi and Fu = 45 ksi for 20 and 18 gauge. Fy = 50 ksi and Fu = 65 ksi for 16, 14 and 12 gauge.
