2.0 USES

The Hilti HSL4 carbon 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 HSL4 anchors comply with Section 1901.3 of the

2021, 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 HSL4 Carbon Steel Heavy Duty Sleeve Anchor:

3.1.1 General: The Hilti HSL4 Carbon Steel Heavy Duty

Expansion Concrete Anchor, designated as the HSL4, is a

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

HSL4 is comprised of seven components which vary slightly

according to anchor diameter, as shown in Figure 1 of this

report. It is available in four 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 and 2 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 HSL4 (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. A product identification code is printed on

the hex bolt of the anchor.

3.1.3 HSL4-G (Stud): The anchor has the same

components and material specifications as the HSL4 (bolt)

with the exception that the bolt is replaced by a carbon steel

threaded rod and nut. A product identification code is printed

on the hex nut of the anchor.

3.1.4 HSL4-B (Torque-Limiting Nut): The anchor has the

same components and material specifications as the HSL4

(bolt) with the addition of a torque cap nut that permits the

proper setting of the anchor without a torque-indicator

wrench. 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. A product identification

code is printed on the bolt.
