FAZ II metal anchor for cracked concrete

fischer
Bolt anchor FAZ II
The power anchor for highest demands

NEW


Bolt anchor FAZ II
For highest demands
Powerful and flexible
The distinctive edge holds the
expansion clip in position even
with reinforcement hits, thus
ensuring safe installation.

With a choice of pre-assembled normal washer
or large washer GS and with washer HBS in
compliance with wood construction standard
DIN 1052 (not pre-assembled).

The protruding hammer-in pin
protects the thread from damage
during setting.

NEW

The eight new sizes of the special cap
nut version (M10 and M12) can be
used for the application on
sophisticated design. They are also
implemented in the ETA assessment.

The interaction of cone and expansion clip significantly
increases load-bearing capacity and makes minimum
edge distance and axial spacing possible.

Variable embedment depths
Enables most accurate adaption on the loads (M 8 - M 16).

Your advantages at a glance
■

With the new ETA assessment for Option 1 the tension loads are
increased up to 10% and the shear loads up to 17%. So fewer
and smaller anchors are required.

■

The minimum embedment depth (see example) makes
considerably shorter drill hole depths possible, thus provides a
noticeably faster installation and less rebar hits.

■

The new cup nut, not only gives the option for a better and
refined optical design but also, ensures an accident free
installation.

■

FAZ II 6: First bolt anchor with drill-hole diameter 6 mm and ETA
Option 1 worldwide, for safe and approved anchorage.

Powerful and flexible
The FAZ II is suitable for pre-positioned and push-through
installation and is also ideal for stand-off installation.

■

■

Experts report for use in concrete C12/15 and C80/95.

The assessment document covers the use of hollow drills and
diamond drills.

Bolt anchor FAZ II K
For highest demands
Short and practical
The 12 sizes of FAZ II K in zinc-plated or
stainless steel versions can be used up
to a fixture thickness of 20 mm.

The shorter bolt with minimum embedment depth is
the economic choice for numerous applications such
as the fixing of cable trays and substructures for façades.

With a choice of normal
washer or large washer GS.

Short and practical

Your advantages at a glance

The FAZ II K is suitable for pre-positioned and push-through
installation.

■

The small drill hole depth of the K-version speeds up installation
even further and reduces the number of reinforcement hits.

■

■

The properties of the FAZ II K considerably minimise the drilling
effort and the hammer blows required to drive in the bolt anchor,
saving energy and installation time.

■

The tried-and-trusted expansion clip ensures a high load-bearing
capacity even with minimum embedment depth. This guarantees
an unbeatable price-performance ratio.

load actions of γL = 1.4 are considered. As an single anchor counts e. g. an anchor with a spacing s ≥ 3 ×hef
and an edge distance c ≥ 1.5 × hef. Accurate data see ETA.
2) F or higher concrete strength classes up to C50/60 higher permissible loads may be possible.

7) Minimum possible axial spacings resp. edge distance while reducing the permissible load.
8) The given loads refer to the European Technical Assessment ETA-05/0069, issue date 03.07.2017. Design of

fischer FIXPERIENCE
The design and information software suite

 The modular design program includes engineering software and
application modules.
 The software is based on international design standards (ETAG 001 and
EC2, such as EC1, EC3 and EC5), including the national application documents. All common force and measurement units are available.
 Incorrect input will be recognized and the software gives tips to get a
correct result. This ensures a safe and reliable design every time.
 The graphical display can easily be rotated through 360°, panned, tilted
or zoomed as required.
 The 3D display gives a detailed and realistic image.
 The “live update” feature helps to keep the program up to date ensuring
you are always working with the latest version.
 Free download and updates at www.fischer.de/fixperience-en
