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
Proof of Performance
  • ETA-02/0044 for individual fixing point, option 7, uncracked concrete

  • ETA-05/0120 for anchors in a redundant non-structural system in non-load-bearing systems, uncracked and cracked concrete, M6-M16

  • Fire resistance: F30, F60, F90 and F120; exposure to fire according to DIN 4102-2:1977-09 (uniform temperature curve)

  • Fire resistance: R30, R60, R90 and R120; TR020 (included in ETA-05/0120)

  • Fire resistance: F30, F60, F90 and F120; exposure to fire according to DIN 4102-2:1977-09 (uniform temperature curve)

  • Fire resistance: R30, R60, R90 and R120; TR020 (included in ETA-05/0120)

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)

  • Suitable for fastening threaded rods, metal structures, metal profiles, grilles, cable conduits, pipes, mounting rails etc.

  • 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 γF = 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.
