- Individual fixing point or anchors in a redundant non-structural system with European Technical Approval in normal weight concrete C20/25 to C50/60 (uncracked concrete only)
- Anchors in a redundant non-structural system in non-load-bearing systems in concrete (size M6, cracked and uncracked concrete)
- For use in concrete < C20/25 and pressure-resistant natural stone (without approval/assessment)
- Fastenings under exposure to fire (size M6 only)
- Suitable for anchoring medium to heavy loads in concrete: Mounting of e.g. metal structures, metal profiles, brackets, base plates, cable conduits, pipes, wooden structures, beams, purlins, fences etc.
- W-FA/A4 (A4 stainless steel) is suitable for use in dry indoor areas or wet rooms and for use outdoors (including in industrial atmospheres and close to the sea), provided that no particularly aggressive conditions are present

| 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. For information on combining tensile and shear loads, on the influence of the edge distance and on anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Annex C. 2) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. | ||||||||||||||
