<br />For shear loads Vappl,ed 5 0.2Va11cwab1e,ASD, the full allowable load in tension is permitted.
<br />For tension loads TappDed 5 0.2Ta11owab1e.ASD, the full allowable load in shear is permitted.
<br />For all other cases:

<br />4.2.3 Installation:
<br />Installation parameters are provided in Table 1 and Figure 2, Figure 5A, Figure 5B, Figure 5C and Figure 5D.
<br />Anchor locations must comply with this report and plans and specifications approved by the code official. The
<br />Hilti KB-TZ2 must be installed in accordance with manufacturer's published instructions and this report. In case
<br />of conflict, this report governs. Anchors must be installed in holes drilled into the concrete using carbide -tipped
<br />masonry drill bits complying with ANSI B212.15-1994, using the Hilti SafeSet System" with Hilti TE-YD or
<br />TE-CD Hollow Drill Bits complying with ANSI B212.15-1994 with a Hilti vacuum in accordance with Figure 6
<br />and Figure 7, or using Hilti SPX-T core bits in accordance with Figure 7. The Hollow Drill Bits are not permitted
<br />for use with the '/.-inch and 3/8-inch diameter KB-TZ2 anchors. The Hilti SPX-T core bits are not permitted for
<br />use with the '/a -inch and 1-inch diameter KB-TZ2 anchors. The minimum drilled hole depth, ho, is given in
<br />Table 1. If dust and debris is removed from the drilled hole with the Hilti TE-YD or TE-CD Hollow Drill Bits, the
<br />DRS attachment system, or compressed air or a manual pump, hnem is achieved at the specified value of
<br />ho noted in Table 1. The anchor must be hammered into the predrilled hole until hno,;, is achieved. The nut must
<br />be tightened against the washer until the torque values specified in Table 1 are achieved, or the anchors may
<br />be installed using the appropriate Hilti Impact Wrench and corresponding Hilti AT Module in accordance with
<br />Figure 7. The Hilti AT Tool system is not permitted for use with the '/a -inch and 1-inch diameter KB-TZ2
<br />anchors. For installation in the soffit of concrete on steel deck assemblies, the hole diameter in the steel deck
<br />must not exceed the diameter of the hole in the concrete by more than '/e inch (3.2 mm). For member thickness
<br />and edge distance restrictions for installations into the soffit of concrete on steel deck assemblies, Figure,
<br />Figure 5B and Figure 5C.
<br />4.3 Special Inspection:
<br />Periodic special inspection is required in accordance with Section 1705.1.1 and Table 1705.3 of the 2024 IBC,
<br />as applicable. The special inspector must make periodic inspections during anchor installation to verify anchor
<br />type, anchor dimensions, concrete type, concrete compressive strength, anchor spacing, edge distances,
<br />concrete member thickness, tightening torque, hole dimensions, anchor embedment and adherence to the
<br />manufacturer's printed installation instructions. The special inspector must be present as often as required in
<br />accordance with the "statement of special inspection." Under the IBC, additional requirements as set forth in
<br />Sections 1705, 1706 and 1707 must be observed, where applicable.
<br />5.0 CONDITIONS OF USE:
<br />The Hilti KB-TZ2 anchors described in this report comply with the codes listed in Section 1.0 of this report, subject
<br />to the following conditions:
<br />5.1 Anchor sizes, dimensions, minimum embedment depths and other installation parameters as set forth in
<br />this report.
<br />5.2 The anchors must be installed in accordance with the manufacturer's published instructions and this report.
<br />In case of conflict, this report governs.
<br />5.3 Anchors must be limited to use in cracked and uncracked normal -weight concrete and lightweight concrete
<br />having a specified compressive strength, fc, of 2,500 psi to 8,500 psi (17.2 MPa to 58.6 MPa), and cracked
<br />and uncracked normal -weight or sand -lightweight concrete over metal deck having a specified compressive
<br />strength, fc, of 3,000 psi to 8,500 psi (20.7 MPa to 58.6 MPa).
<br />5.4 The values of f,; used for calculation purposes must not exceed 8,000 psi (55.1 MPa).
<br />5.5 The concrete shall have attained its minimum design strength prior to installation of the anchors.
<br />5.6 Strength design values must be established in accordance with Section 4.1 of this report.
