The FBN II is fire-resistant to F120.
A key feature of the FBN II is its long threaded
length. This permits considerable flexibility in
terms of embedment depth and also enables
the installation of stand-off fixings. It is also
easier to install than many competitor
products, requiring fewer hammer strokes and
just a few turns of the nut.
A popular and unique fixing is the fischer FNA
II Nail Anchor, which has been developed to
enable straightforward anchoring in any
conditions. Drill the hole, strike three times
with a hammer, and the FNA II sits tight. It’s
as simple as that – and the unique aspect of
this anchor is its ability to combine ease of
installation with a high degree of safety, since
it is the first anchor of this type to boast a

capability. The FH II offers up to 21 per cent
higher permissible tensile load capacity and
double the shear load capacity of its
predecessor, the FH.
The fixing achieves this impressive
performance as a result of the interaction
between the expansion sleeve and the cone.
When the screw or nut is tightened, the cone
is pulled into the expansion sleeve and
tightens against the inside of the drill hole.
This fixing is particularly suitable for use in
situations where the aesthetic appearance is
important. Unlike with bolt anchors, where a
length of threaded bolt can protrude from the
