1 The tabulated load values are for the low-velocity fasteners only based on testing in accordance with ICC-ES AC 70 and ASTM E1190 . Allowable loads are calculated based on a safety factor of at least 5.0 . Some |
conditions like high wind loads , shock or fatigue may require a different safety factor . Wood or steel members connected to the substrate must be investigated in accordance with accepted design criteria . |
2 Multiple fasteners are recommended for any attachment . |
3 This allowable load value for the X-U fastener also applies to normal weight hollow core concrete slabs with f ′ c of 6600 psi and minimum face shell thickness of 1-3 / 8 in . |
