1 The tabulated allowable load values are for the low-velocity fasteners only , using a safety factor that is greater than or equal to 5.0 , calculated in accordance with ICC-ES AC70 .
Wood or steel members connected to the substrate must be in investigated in accordance with accepted design criteria . 2 Unless otherwise noted , allowable loads are applicable to static and seismic loads in accordance with Annex A of ICC-ES AC70 . 3 Low-velocity fasteners shall be driven to where the point of the fastener penetrates through the steel base material in accordance with Section 3.2.2.3 , except as noted in this table . 4 Unless otherwise noted , steel base material must have minimum yield and tensile strengths ( F y and F u ) equal to 36 ksi and 58 ksi , respectively .
5 Steel base material must have minimum yield and tensile strengths ( F y and F u
) equal to 50 ksi and 65 ksi , respectively . 6 Fasteners installed into 3 / 8 " or thicker base steel require 0.320 " minimum penetration depth . 7 Based upon minimum penetration depth into the steel of 15 / 32 ". 8 Based upon minimum penetration depth into the steel of 1 / 4 ". 9 Refer to guidelines for fastening to steel , Section 3.2.2 , for application limits . 10 For steel-to-steel connections designed in accordance with Section J5 of AISI S100 , the tabulated allowable load may be increased by a factor of 1.25 . 11 Refer to guidelines for fastening to steel , Section 3.2.2 , for application limits . 12 Multiple fasteners are recommended for any attachment . 13 Published values may vary from values in ICC-ESR

1 Allowable load values are based on a safety factor of 3.0 . 2 Allowable pullover capacities of sheet steel should be compared to the allowable fastener tensile load capacities in concrete , steel , and masonry to determine controlling resistance load . 3 Allowable shear bearing capacities of sheet steel should be compared to allowable fastener shear capacities in concrete , steel or masonry to determine controlling resistance load . 4 Data is based on the following minimum sheet steel properties , F y
= 33 ksi , F u
= 45 ksi ( ASTM A653 material ).
