Female thread anchor with metric thread for economical anchoring in concrete, A4 stainless steel

Small drill hole depth

High working loads

Optical installation control and hand protection during assembly with the marking tool

The machine tool facilitates and speeds up installation

Immediate load-bearing capacity - no waiting

Fixture can easily be removed at any time

The attachment can be anchored with a fastening screw or a threaded rod

No installation torque required

The stop drill bit in combination with the clip-on expander tool facilitates and accelerates installation. The matching drill holes make the installation even more secure

Application area

Individual fixing point: Normal weight concrete C20/25 to C50/60 (uncracked concrete)

Anchors in a redundant non-structural system: Anchorage of non-load-bearing systems (M6-M16, cracked and uncracked concrete)

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

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

W-ED/HCR (HCR high corrosion-resistant steel) can be used in areas where there is a very high risk of corrosion (e.g. indoor swimming pool atmosphere, road tunnels, poorly ventilated car parks, or parts that are immersed in seawater or in coastal atmospheres)

¹⁾ The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of γ_F = 1.4 have been taken into account. Please refer to the European Technical Approval Guidelines (ETAG), Appendix C, for information on combining tensile and shear loads, the influence of the edge distance and groups of anchors. ²⁾ The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. ³⁾ The admissible loads were determined without axial influence and the influence of the edge distance. ⁴⁾ Fire resistance rating: Drop-in anchor W-ED/A4 in conjunction with screws made of stainless steel A4.

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
