BUILDING MATERIALS
Approved for:
▪ Concrete C20/25 to C50/60, noncracked
Also suitable for:
▪ Concrete C12/15, non-cracked
▪ Natural stone with dense structure
ADVANTAGES
APPLICATIONS
FUNCTIONING
▪ The internal threaded anchor RG MI
allows for the surface flush removal
and reuse of the fixing point. It
therefore offers great flexibility.
▪ The metric internal thread allows for
the use of standard metric screws or
threaded rods for the ideal
adaptation to suit the intended use.
▪ The pre-portioned resin capsule is
especially economical for individual
applications.
▪ The glass particles of the capsule
body rough up the drill hole wall
during the setting process. This
minimises the amount of cleaning
required and allows for installation
under extreme conditions, for
example in water-filled drill holes.
▪ Removable fixings
▪ Temporary fixings, e.g. for machines
▪ Scaffold anchoring
▪ The resin anchor R is suitable for prepositioned installation when
combined with the internal threaded
anchor RGMI.
▪ The 2-component resin capsule RM
contains quick-setting styrene-free
vinyl ester resin and hardener.
▪ The internal threaded anchor RGMI
is set using a hammer drill and the
accompanying setting tool in
rotating and hitting motions.
▪ During setting, the oblique edge of
the internal threaded anchor
destroys the capsule, and mixes and
activates the mortar.
▪ The mortar bonds the entire surface
of the internal threaded anchor with
the drill hole wall and seals the drill
hole.
