For SI: 1 inch = 25.4 mm, 1 lbf = 4.4 N, 1 psi = 6895 Pa.
1
Fasteners must not be driven until the concrete has reached the specified compressive strength.
2
Concrete material thickness at the point of penetration must be a minimum of 3 inches, except as shown in Figures 10 through 13.
3
Deck panel must have a minimum No. 20 gage (0.0359 inch) base-metal thickness and a minimum yield strength of 33,000 psi.
4
Nailhead Standoff, h
NVS
, must be less than or equal to
1
/
4
inch for the X-DR, less than or equal to
5
/
16
inch for the X-MW ALH assemblies, less than or equal to

8
inch for the X-HS U32 hanger assembly and as indicated in the Hilti installation instructions. See
Figures 6, 7 and 8, as applicable.
5
Allowable loads apply to X-HS threaded rod hanger assemblies with either the

- or
3

-inch-diameter internally threaded hole.
6
See Figures 9a, 9b and 9c for load directions for the X-HS assemblies.
7
See Figures 10 through 13 for nominal flute dimensions, fastener locations, and load orientations.
8
Allowable loads for 45-degree applications are based on testing. For allowable loads at other angles of installation, refer to Section 4.1.2.
9
Allowable loads are for concrete with minimum f′
c
of 3,000 psi, unless otherwise noted.
10
Allowable loads are for concrete with minimum f′
c
of 3,500 psi.
