Property evaluated: Structural 2.0 USES Hilti X-HS low-velocity, powder-actuated, threaded rod hanger assemblies are used as alternatives to the cast-inplace anchors described in IBC Section1908 for placement in concrete, and the welds and bolts used to attach materials to steel, described in IBC Sections and , respectively. The assemblies are used to connect threaded steel rods to the supporting material. The hanger assemblies may be used where an engineered design is submitted in accordance with IRC Section R DESCRIPTION 3.1 X-HS Threaded Rod Hanger Assembly: The Hilti X-HS threaded rod hanger assembly consists of a Hilti X-U low velocity, powder-actuated fastener (recognized in RR with two premounted washers (one of zinc-plated steel, one of plastic), and a premounted cold-formed steel bracket (threaded rod hanger) having a 1 / 4 - or 3 / 8 -inch-diameter (6.4 or 9.5 mm) internally threaded hole to accommodate connection of 1 / 4 - or 3 / 8 -inchdiameter (6.4 or 9.5 mm) UNC threaded steel rods, respectively. The X-HS U19 and X-HS U32 hanger assemblies described in this report, include Hilti X-U19 and X-U32 fasteners, respectively, recognized in RR The X-U19 and X-U32 fasteners have shank lengths of 0.75 inch (19 mm) and 1.26 inches (32 mm), respectively. The threaded rod hangers are manufactured from mild carbon steel with a zinc coating in accordance with Hilti s specifications. See Figure 1 for an illustration of the X-HS threaded rod hanger assembly. 3.2 Substrate Materials: Steel: Structural steel used in supports must comply with the minimum strength requirements of ASTM A36, A572 Grade 50 or A992, and must have a minimum thickness of 3 / 16 -inch (4.76 mm) Normal-weight Concrete: Normal-weight concrete must be stone-aggregate and comply with IBC Chapter 19 or IRC Section R402.2, as applicable. The minimum concrete compressive strength at the time of fastener installation is noted in Table Lightweight Concrete: Lightweight concrete must be sand-lightweight complying with IBC Chapter 19. The minimum concrete compressive strength at the time of fastener installation is noted in Table Steel Deck Panels: Steel deck panels must conform to a code-referenced material standard, with the minimum thickness and minimum yield strength noted in Table 3. See Figures 4 through 6 for panel configuration requirements. 4.0 DESIGN AND INSTALLATION 4.1 Design: Allowable Loads: The allowable tension, shear and 45-degree-angle loads for X-HS threaded rod hanger assemblies installed into steel are provided in Table 1. The allowable tension, shear and 45-degree-angle loads for X-HS threaded rod hanger assemblies installed into normal-weight concrete are provided in Table 2. The allowable tension, shear and 45-degree-angle loads for X-HS threaded rod hanger assemblies installed into sandlightweight concrete and into sand-lightweight concrete filled steel deck panels are provided in Table 3. For other angles of installation, allowable loads for assemblies subjected to combined shear and tension forces must be determined using the following equation: ICC-ES Evaluation Reports are not to be construed as representing aesthetics or any other attributes not specifically addressed, nor are they to be construed as an endorsement of the subject of the report or a recommendation for its use.

V a = Allowable shear load, lbf (N). The stress increases and load reductions described in IBC Section are not allowed for wind loads acting alone or when combined with gravity loads. No increase is allowed for vertical loads acting alone. Allowable loads apply to the connection of the X-HS Hanger Assembly to the base material only with threaded rod installed. Design of the connection of the X-HS Hanger Assembly to the suspended material must comply with the applicable requirements of the IBC Seismic Considerations: Use with Structural Components: Resistance to seismic loads is outside the scope of this report. Therefore, the suitability of the Hilti X-HS Hanger Assemblies for use with structural components that are subjected to seismic loads is outside the scope of this report Use with Nonstructural Components: Seismic load resistance is outside the scope of this report, except when used with architectural, mechanical and electrical components described in Section of ASCE 7 and as follows: Concrete Base Materials: The X-HS Hanger Assemblies fastened to concrete may be used to support acoustical tile or lay-in panel suspended ceiling systems, distributed systems and distribution systems where the service load on any individual X- HS Hanger Assembly does not exceed the lesser of 90 lbf (400 N) or the published allowable load shown in Table 2 or 3, as applicable. Steel Base Materials: The X-HS Hanger Assemblies fastened to steel may be used where the service load on any individual X-HS Hanger Assembly does not exceed the lesser of 250 lbf (1112 N) or the published allowable load shown in Table Installation: General: The X-HS threaded rod hanger assemblies must be installed in accordance with this report and the Hilti, Inc., published installation instructions, including those shown in Figure 2. A copy of these instructions must be available on the jobsite at all times during installation. Installation is limited to dry, interior locations. Fastener placement requires the use of a low-velocity powder-actuated tool in accordance with Hilti, Inc. recommendations. Nailhead standoff distance must be as noted in the footnotes to the tables and as shown in Figure 2. Installers must be certified by Hilti and have a current, Hilti-issued, operator s license Fastening to Steel: When installation is in steel, minimum spacing between fasteners must be 1 inch (25.4 mm) and minimum edge distance must be 1 / 2 inch (12.7 mm) Fastening to Concrete: Fasteners must be driven into the normal-weight or sand-lightweight concrete after the concrete attains the specified concrete compressive strength. Unless otherwise noted, minimum spacing between fasteners must be 4 inches (102 mm) and minimum edge distance must be 3 inches (76 mm). Unless otherwise noted in this report, concrete thickness must be a minimum of 3 inches (76 mm) Fastening to Sand-lightweight Concrete Filled Steel Deck Panels: Installation in sand-lightweight concrete filled steel deck panels must comply with Figures 4 through 6. Minimum distances from fastener centerline to rolled deck panel flute edges must be as depicted in Figures 4 through CONDITIONS OF USE The Hilti X-HS threaded rod hanger assemblies described in this report comply with, or are suitable alternatives to what is specified in, those codes listed in Section 1.0 of this report, subject to the following conditions: 5.1 The hanger assemblies are manufactured and identified in accordance with this report. 5.2 Hanger assembly installation complies with this report and the Hilti, Inc., published instructions. In the event of conflict between this report and Hilti, Inc., published instructions, this report governs. 5.3 Calculations demonstrating that the actual loads are less than the allowable loads described in Section must be submitted to the code official for approval. The calculations must be prepared by a registered design professional where required by the statutes of the jurisdiction in which the project is constructed. 5.4 Refer to Section for seismic considerations. 5.5 The use of the hanger assemblies is limited to installation in uncracked concrete. Cracking occurs when f t > f r due to service loads or deformations. 5.6 Use of the hanger assemblies is limited to dry, interior locations. 5.7 Installers must be certified by Hilti, Inc., and have a current, Hilti-issued, operator s license. 6.0 EVIDENCE SUBMITTED Data in accordance with the ICC-ES Acceptance Criteria for Fasteners Power-driven into Concrete, Steel and Masonry Elements (AC70), dated February IDENTIFICATION The word Hilti and the designation X-HS are stamped on the hanger.
