HALFEN HSR
HALFEN Bolts with nib
Note: The T-head bolts used in HALFEN Channels must display the manufacturer's mark "H" or "HALFEN".
The use of any other bolts is not allowed.
Notch marking:
HALFEN Bolts have notches at the end of the shaft, (HSR-bolts have two notches) these are to identify
the bolt and also to check correct installation.
After fi nal tightening of the bolt, the notches must be perpendicular to the longitudinal channel axis.
Load capability in channel longitudinal direction:
HSR Bolts are suitable for bearing loads in all directions. They are only to be used with hot-rolled channel
profi les in carbon steel, mill fi nished or hot-dip galvanized (see table on page 3).
Hot-rolled channel profi le:
Combination bolt - channel:
Note: Only use HALFEN Bolts in combination with the hexagon-nuts
which are supplied together with the bolts.

Insert the HALFEN Bolts into the channel slot. Turn the HALFEN Bolt 90°
clockwise to lock it in position (check the notches are perpendicular
to the channel's longitudinal axis).

Position of the bolts: Installation of HALFEN Bolts in the excess length of
the channels is not allowed.

Always use the right tightening torque T
The tightening torques depend on bolt type, bolt size, channel type and
assembly variant. Refer to the planning documents or engineer's specifi ca-
tion. The tightening torques are shown in the provided tables.

Assembly variants:
Non-fl ush installed cast-in channels.
If the face of the channel is not fl ush with the concrete surface
(e.g. due to insuffi cient fi xing to the formwork) then appropriate
shims must be used between the face of the channel and the back
of the component to bridge the gap.
Note: the admissible bending moment of the HALFEN Bolt must
not be exceeded.
Shimming with stand-off assembly
US or VUS Washers should always be used under the nut when
tightening the hex nut directly against the channel face.
SIC Lockwashers provide additional safety against the bolts
being loosened.
