3.1.3 HSL-3-G (Stud): The anchor has the same
components and material specifications as the HSL-3 (bolt)
with the exception that the bolt is replaced by a threaded
rod of carbon steel per DIN EN ISO 898-1 Grade 8.8 and a
nut of carbon steel per DIN 934 Grade 8. A screwdriver
slot is provided on the exposed end of the threaded rod.
3.1.4 HSL-3-B (Torque-Indicator Bolt): The anchor has
the same components and material specifications as the
HSL-3 (bolt) with the addition of a torque cap nut that
permits the proper setting of the anchor without a
torque-indicator wrench. The torque cap is zinc alloy
complying with DIN 1743. A hexagonal nut is fastened to
the bolt head by three countersunk rivets. When the
anchor is tightened, the torque is transmitted to the cap.
When the torque corresponding to the required anchor
expansion is attained, the three countersunk rivets shear
off. The torque cap nut breaks free exposing the
permanent hex nut.
3.1.5 HSL-3-SH: The anchor has the same components
and material specifications as the HSL-3 (bolt) with the
exception that the bolt head is configured to accept a
hexagonal Allen wrench.
3.1.6 HSL-3-SK: The anchor has the same components
and material specifications as the HSL-3 (bolt) except that
the bolt head is configured for countersunk applications, is
configured to accept a hexagonal Allen wrench and is
provided with a conical washer. The bolt is carbon steel
per DIN ISO 4759-1 and DIN EN ISO 898-1, Grade 8.8.
3.2 HSL-3-R Stainless Steel Heavy Duty Sleeve
Anchor:
3.2.1 General: The Hilti HSL-3-R Stainless Steel Heavy
Duty Expansion Concrete Anchor, designated as the HSL-
3-R, is a torque-set, sleeve-type mechanical expansion
anchor. The HSL-3-R is comprised of seven components
which vary slightly according to anchor diameter, as shown
in Figure 1 of this report. It is available in three head
configurations, illustrated in Figure 2 of this report.
Dimensions and installation criteria are set forth in
Tables 1, 4, and 5 of this report. Application of torque at
the head of the anchor causes the cone to be drawn into
the expansion sleeve. This in turn causes the sleeve to
expand against the wall of the drilled hole. The ribs on the
collapsible element prevent rotation of the sleeve and cone
during application of torque. Application of the specified
installation torque induces a tension force in the bolt that is
equilibrated by a precompression force in the concrete
acting through the component being fastened. Telescopic
deformation of the collapsible element prevents buildup of
precompression in the anchor sleeve in cases where the
shear sleeve is in contact with the washer, and permits the
closure of gaps between the work surface and the
component being fastened. Application of tension loads
that exceed the precompression force in the bolt will cause
the cone to displace further into the expansion sleeve
(follow-up expansion), generating additional expansion
force.
3.2.2 HSL-3-R (Bolt): The anchor consists of a stainless
steel stud bolt, stainless steel washer, stainless steel
sleeve, collapsible plastic sleeve, stainless steel expansion
sleeve and stainless steel cone. This anchor is available in
stainless steel only. The material specifications are as
follows:
Bolt: Stainless steel per DIN EN 10088-3
Washer: Stainless steel per DIN EN 10088-3.
Expansion cone: Stainless steel per ASTM
A511/A511M.
Expansion sleeve: Stainless steel per ASTM
A276/A276M.
Steel sleeve: Stainless steel per ASTM A511/A511M.
Collapsible sleeve: Acetal polyoxymethylene (POM)
resin.
3.2.3 HSL-3-GR (Stud): The anchor has the same
components and material specifications as the HSL-3-R
(bolt) with the exception that the bolt is replaced by a
threaded rod of stainless steel per AISI 316. A screwdriver
slot is provided on the exposed end of the threaded rod.
3.2.4 HSL-3-SKR: The anchor has the same components
and material specifications as the HSL-3-R (bolt) except
that the bolt head is configured for countersunk
applications, is configured to accept a hexagonal Allen
wrench and is provided with a conical stainless steel
washer.
3.3 Concrete:
Normal-weight and lightweight concrete must conform to
Sections 1903 and 1905 of the IBC, as applicable.
4.0 DESIGN AND INSTALLATION
4.1 Strength Design:
4.1.1 General: Design strength of anchors complying with
the 2018 and 2015 IBC, as well as Section R301.1.3 of the
2018 and 2015 IRC must be determined in accordance
with ACI 318-14 Chapter 17 and this report.
Design strength of anchors complying with the 2012 IBC,
and the 2012 IRC, must be in accordance with ACI 318-11
Appendix D and this report.
