2.0 USES

The Hilti HSL-3 carbon steel and HSL-3-R stainless steel

heavy duty expansion anchors are used as anchorage to

resist static, wind, and seismic tension and shear loads in

cracked and uncracked normal-weight and lightweight

concrete having a specified compressive strength

2,500 psi  f

′

 8,500 psi (17.2 MPa  f

′

 58.6 MPa)

[minimum of 24 MPa is required under ADIBC Appendix L,

Section 5.1.1].

The Hilti HSL-3 and HSL-3-R anchors comply with

Section 1901.3 of the 2018 and 2015 IBC, Section 1909 of

the 2012 IBC, and Section 1912 of the 2009 IBC. The

anchor system is an alternative to cast-in-place anchors

described in Section 1908 of the 2012 IBC, and Section

1911 of the 2009 IBC. The anchors may also be used

where an engineered design is submitted in accordance

with Section R301.1.3 of the IRC.

3.0 DESCRIPTION

3.1 HSL-3 Carbon Steel Heavy Duty Sleeve Anchor:

3.1.1 General: The Hilti HSL-3 Carbon Steel Heavy Duty

Expansion Concrete Anchor, designated as the HSL-3, is a

torque-set, sleeve-type mechanical expansion anchor. The

HSL-3 is comprised of seven components which vary

slightly according to anchor diameter, as shown in Figure 1

of this report. It is available in five head configurations,

illustrated in Figure 2 of this report.

All carbon steel parts receive a minimum 5 μm

(0.0002 inch) thick galvanized zinc plating.

Dimensions and installation criteria are set forth in

Tables 1, 2 and 3 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.

3.1.2 HSL-3 (Bolt): The anchor consists of a stud bolt,

steel washer, steel sleeve, collapsible plastic sleeve, steel

expansion sleeve and steel cone. This anchor is available

in carbon steel only. The material specifications are as

follows:

 Bolt: Carbon steel per DIN EN ISO 898-1, Grade 8.8

 Washer: Carbon steel per DIN EN 10025.

 Expansion cone: Carbon steel per DIN 1654-4.

 Expansion sleeve: Carbon steel, M8-M16 per DIN

10139, M20-M24 per DIN 2393-2.

 Steel sleeve: Carbon steel per DIN 2393-1.

 Collapsible sleeve: Acetal polyoxymethylene (POM)

resin.
