Ideal for fastening mounting rails, panel materials or fire-protection panels in concrete, A4 stainless steel
  • Extremely flexible to use due to three anchoring depths

  • Fastening can be adjusted up to twice after installation, for example in order to align anchor plates or rails (please refer to the assembly guide)

  • High loads

  • Smallest axial and edge clearance due to very low expansion effect

  • Very fast and easy assembly and immediately load-bearing
Proof of Performance

  • Static and quasi-static effects (∅6)

  • Seismic effect, performance category C1 (∅6)

  • Fire resistance R30, R60, R90, R120


European Technical Assessment ETA-16/0128 for anchors in a redundant non-structural system:


  • Cracked and non-cracked concrete, (∅6)

  • Hollow-core prestressed concrete ceilings C30/37 - C50/60, (∅6)

  • Fire resistance R30, R60, R90, R120


Fire resistance rating when exposed to fire according to the uniform temperature time curve in masonry (Mz, KSL, KS), and reinforced concrete, (∅6) - expert report no. 2101/173/18 - 2018

Notice

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

Application area

Fixing point with approval (∅6):


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



Anchors in a redundant non-structural system with approval:


  • In normal weight concrete C20/25 to C50/60 (cracked and non-cracked concrete), (∅6)

  • In hollow-core prestressed concrete ceilings C30/37 - C50/60, (∅6)


Pan head with attractive head geometry, ideally suited for fastening medium loads in concrete:


  • Fastening of e.g. mounting rails, panels, sheets, fire protection panels, handrails, metal profiles, brackets, wooden substructures etc. in in-place installation

  • Fastenings under seismic conditions in earthquake areas

  • Fastenings under exposure to fire


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



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

For cleaning drill holes with a smaller diameter
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
04076
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
Price for 100 units
Price for 1000 units
The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.
In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
