Example
Hilti Anchor Channel with serrated channel lips (HAC-30 and
HAC-T) is a cast-in solution for applications that require on-site
adjustability and slip resistances along the long axis of the
anchor channel resulting from loads such as seismic wind, live,
gravity or other.
HAC-30 profile is cold formed and although its name does not
include "-T", the profile comes with serrated lips. HAC-30 is for
low range loads.
The innovative manufacturing technology allows HAC-T to offer
slip resistances that require up to 58 percent lower installation
torques than existing technologies without compromising the
price point or performance of the anchorage. Because of the
lower installation torque, the installation time per connection
can be reduced and muscle fatigue may be avoided. HAC-30
and HAC-T are fully covered by the International Council Code
Evaluation Service Report 3520 (ESR-3520).
Hilti Anchor Channels with serrated channel lips (HAC-T) are
offered in two channel profile sizes; HAC-T50 and HAC-T70.
Hilti Serrated Channel Bolts (HBC-T) are suitable for all HAC-T
profiles. HAC-T50 and HAC-T70 profiles are utilized in all
different types of anchor channels.
Hilti Serrated Anchor Channel (HAC-T) come with a serrated
channel profile and rounded head anchors. Pre-formed
serrations allows the channel to resist longitudinal shear loads
via a positive connection with lower installation torque.
The standard portfolio consists of HAC30, HAC-T50, and HAC-
T70 channels profiles with pre-defined channel length, rebar
lengths, number of anchors, and defined rebar diameter. Non-
standard anchor channels (i.e. custom channel length, rebar
length, number of rebars etc.) can be provided upon request.
Refer to section 2.4, 2.5, and 2.6 for additional information about
standard items lead times, and custom anchor channels.
