High working loads with easy assembly and installation. Ideal for fastening facilities for proper building function in open buildings or outdoors.
  • With combination sleeve, internal thread M8/M10

  • Made from A4 stainless steel

  • The fastest type of fastening for medium to heavy loads, especially for installations involving technical building equipment

  • Less drilling and installation effort

  • The new thread geometry ensures smooth screwing into concrete and thus greater efficiency during assembly

  • Smallest axis and edge distances due to very low expansion effect

  • Broad range of applications
Proof of Performance

European Technical Assessment ETA-22/0123 for individual fixing point, option 1, cracked and uncracked concrete:


  • Static and quasi-static action (dia. 6)

  • Seismic action, performance category C1 (dia. 6)

  • Fire resistance R30, R60, R90, R120
Notice

When installing with a tangential impact driver, the recommended maximum rated torque must be observed. When used outdoors, the drill hole can be sealed with WIT-BS injectable mortar.

Application area
Pipe suspensions

Application area

Individual fixing point with ETA/approval (dia. 6):


In normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete)



The simplest solution for suspended installations with threaded rods in sizes M8 and M10. Very efficient fastening solution in concrete for numerous applications involving technical building equipment such as in sanitary, air-conditioning and electrical installation. A4 stainless steel design for use outdoors, in open buildings, in car parks, underground garages or tunnels (corrosion resistance class CRC III).



Ideal for fastening medium loads in concrete:


  • Fastening of e.g. single pipe and ventilation installations, suspended ceiling substructures, suspended cable and pipe sections

  • Fastenings under seismic conditions in earthquake-prone areas

  • Fastenings under exposure to fire


W-BS 2/A4 (A4 stainless steel) can be used in dry indoor conditions, outdoors (including in industrial atmospheres and coastal areas) or in damp rooms, provided that no particularly aggressive conditions are present.



For use in concrete < C20/25 and pressure-resistant natural stone (without ETA/approval)

1) The partial safety factors of the resistances yM regulated in the approval/evaluation and a partial safety factor of the actions of γF = 1.4 have been taken into account. For information on combining tensile and shear loads, on the influence of the edge distance and on anchor groups, please refer to the appropriate guidelines e.g. DIN EN 1992-4.
2) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths.
3) Only for statically indeterminate non-load-bearing systems (anchors in a redundant non-structural system) in accordance with EN 1992-4 and only in dry indoor conditions.

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.
The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
