2 HILTI, Inc. RE: Hilti Low-Velocity Power Driven Fasteners b) Concrete base materials: The Hilti fasteners installed in 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 fastener does not exceed the lesser of 90 lbf or the published allowable load shown in Tables of the attached ICC-ES report, as applicable. c) Steel base materials: When the Hilti fasteners are installed in steel and are subjected to seismic loads, the most critical load applied to each individual fastener must be determined from the applicable equations in IBC Section or Section , and must not exceed the allowable seismic loads shown in Table of attached report. Recognition of the Hilti fasteners for use in design of lateral force resisting systems, such as shear walls and diaphragms, is outside the scope of this report. d) For interior, nonstructural walls that are not subject to sustained tension loads and are not a bracing application, the power-driven fasteners may be used to attach steel track to concrete or steel in all Seismic Design Categories. In Seismic Design Categories D, E and F, the allowable shear load due to transverse pressure shall be no more than 90 pounds when attaching to concrete; or the allowable loads in Table of attached report when attaching to steel. Substantiating calculations shall be submitted addressing the fastener- to-base-material capacity and the fastener-to attached-material capacity. Interior nonstructural walls are limited to locations where bearing walls, shear walls or braced walls are not required by the approved plans. The design load on the fastener must not exceed the allowable load established in the attached ICC-ES report for the concrete or steel base material. 2. The fasteners are used to attach non-building components including but not limited to drywall tracks, wood, light gage steel, sprinkler pipes, furniture, cabinets, sheet metal duct work, electrical conduits, cable trays, cables, lighting, wood sill plates, acoustical ceiling, light gauge framing, non-bearing-non-structural interior partitions, and other fixtures to normal-weight and structural sand-lightweight concrete, metal decks with structural sand-lightweight concrete fill, concrete masonry units (CMUs) and steel base materials.. The fasteners shall not be used in cracked concrete or cracked masonry. 4. The allowable values listed in the attached report and tables are for the fasteners only. Connected members shall be checked for their capacity (which may govern). 5. The low velocity fasteners installed through the underside of steel deck at the ribs and into minimum 000 psi lightweight concrete shall have minimum edge distance as specified in Section of attached report. Concrete fill above top ribs shall be 2-/2 inches minimum. Refer to Figures, 2 and of the ICC-ES ESR-66 for details. RR Page 2 of 4

3 HILTI, Inc. RE: Hilti Low-Velocity Power Driven Fasteners 6. When installation is in concrete, minimum spacing between fasteners shall be 4 inches on center and minimum edge distance shall be inches. Concrete thickness must be a minimum of three times the embedment depth of the fastener. For CMUs, no more than one power driven fastener may be installed per individual CMU cell. 7. Allowable loads must be in accordance to Section 4. of the attached ICC ES ESR-66. Calculations showing that the applied loads are less than the maximum allowable loads must be submitted to the structural plan check division for review and approval. The calculations must be prepared by a civil or structural engineer registered in the State of California. 8. The fasteners shall be installed per the manufacturer's instructions, a copy of which shall be available at each job site. 9. Hilti X-CR stainless steel power driven fasteners are permitted for use in exterior, damp environments. All other fasteners in this report are limited to installation in dry, interior environments, including those exterior walls protected by an exterior wall envelope. 0. Hilti X-CR fasteners may be installed in contact with preservative-treated wood, as set forth in the applicable code.. Hilti carbon steel fasteners in contact with fire retardant-treated wood may be used in contact with fire-retardant-treated wood in dry, interior locations only, in accordance with Section of the 204 LABC. Under 2008 LABC, use of Hilti carbon steel fasteners in contact with preservative-treated wood or fire-retardant-treated wood is not permitted. 2. All fasteners are identified by an H imprinted on the fastener head. Where applicable the word Hilti is stamped on the steel washers. All fasteners are packaged in containers noting the fastener type, size, manufacturer s name, and evaluation report number (ESR- 66). DISCUSSION The clerical modification is to update company contact person and phone number. The technical modification is to update allowable seismic loads for EDS, DS and X-CR fasteners installed in steel base materials. Increased allowable loads for X-C fasteners installed in concrete have also been added due to increased hardness of fastener. The new X-C fasteners can be distinguished from original fasteners by black collating strips or guidance washers. The report is in compliance with the 204 Los Angeles City Building Code. The approval is based on tests in accordance with ICC-ES Acceptance Criteria for Fasteners Power-driven into Concrete, Steel and Masonry Elements (AC70) dated October 202. RR Page of 4

Allowable Loads: The most critical applied loads, excluding seismic load effects, resulting from the load combinations in IBC Section or must not exceed the allowable loads. For fasteners which are subjected to seismic loads, see Section 4.. for additional information. The allowable tension and shear loads, along with fastener descriptions and shank diameters for powerdriven fasteners installed in structural steel base materials, are shown in Table. The allowable tension and shear loads with minimum required embedment depths, along with fastener descriptions and shank diameters for fasteners installed in normal-weight and sand-lightweight concrete base materials, are shown in Tables 2,, and 4. The allowable tension and shear loads with minimum required embedment depths, along with fastener descriptions and shank diameters, for fasteners installed in concrete masonry units (CMUs), are shown in Table 5. The stress increases and load reductions described in IBC Section 605. are not allowed. Allowable loads apply to the connection of the fastener to the base material only. Design of the connection of the fastener to the attached material must comply with the applicable requirements of the IBC. Allowable loads for fasteners subjected to combined shear and tension forces are determined by the following formula: (p/p a ) + (v/v a ) where: p P a = Actual tension load, lbf (N). = Allowable tension load, lbf (N). v = Actual shear load, lbf (N). V a = Allowable shear load, lbf (N) Attachment of Wood to Steel, Concrete, or Masonry: Reference lateral design values for fasteners determined in accordance with Part of ANSI/AF&PA NDS are applicable to Hilti fasteners of equal or greater diameters. The wood element must be considered to be the side member. The fastener bending yield strength must be the value noted in the NDS based on the fastener diameter.
