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 . 2 Multiple fasteners are recommended for any attachment . Threaded or smooth rod must be investigated in accordance with accepted design criteria . 3 Allowable loads for 45-degree applications are based on testing . For allowable loads at other angles of installation , refer to Section 3.2.1.8 . 4 Nail stand-off must be less than or equal to 0.2-inch , testing was done using concrete with 3,500 psi compressive strength

1 The tabulated allowable load values are calculated using a safety factor that is greater than or equal to 5.0 , in accordance with ICC-ES AC70 . Multiple fasteners are recommended for any attachment . Threaded rod must be investigated in accordance with accepted design criteria .
2 The steel deck profile for the 3 " deep composite floor deck has a minimum thickness of 20 gauge ( 0.0358 ") and a minimum F y
= 33 ksi . Lower and upper flute width must be a minimum of 3-7 / 8 ". Figure 1 in Section 3.2.1.6 shows the nominal flute dimensions , fastener locations and load orientations for the deck profile . Structural lightweight concrete fill above top of steel deck must be minimum 3-1 / 4 ".
3 The steel deck profile for the 1-1 / 2 " deep composite floor deck has a minimum thickness of 20 gauge ( 0.0358 ") and a minimum F y
= 33 ksi . Lower flute and upper flute widths must be a minimum of 1-3 / 4 " and 3-1 / 2 ", respectively . This deck may also be inverted as shown in Figure 3 in Section 3.2.1.6 . Figures 2 and 3 in Section 3.2.1.6 show the nominal flute dimensions , fastener locations and load orientations for the deck profile . Structural lightweight concrete fill above top of steel deck must be minimum 2-1 / 2 ".
4 Nailhead Standoff , h NVS
, must be less than or equal to 3 / 8 " for the X-HS U32 hanger assembly . Reference Section 3.2.16.4 . 5 Allowable loads apply to X-HS threaded rod hanger assemblies with either the 1 / 4 " or 3 / 8 " diameter internally threaded hole . 6 Allowable loads for 45-degree applications are based on testing . For allowable loads at other angles of installation , refer to Section 3.2.1.8 . 7 Values shown for the X-HS threaded rod hanger assembly are for use with the X-U powder-actuated fastener .
