- Quick and easy installation
- Less drilling required thanks to reduced effective anchorage depth of 25 mm
- Easy insertion: Simply hammer in - no torque required
- No special drills or setting tools required
- Push-through installation
- Very low edge distances and spacings possible
- Torque-controlled expanding anchor — expands when subjected to load
- Multiple attachment of non-load-bearing systems in concrete: European Technical Approval ETA-11/0339
- Fire resistance: R30, R60, R90, R120 (anchoring base: concrete C20/25 to C50/60): Technical Report TR 020 "Evaluation of anchorages in concrete concerning resistance to fire" (included in ETA-11/0339)
The nail anchor offers the benefits of a bolt anchor while also being easy to install; the nail anchor is simply knocked into the drill hole through the attached part.

Anchors in a non-structural system based on a redundant design with approval in cracked concrete (tensile zone) and non-cracked concrete (compression zone)
- E.g. lightweight ceiling cladding and suspended ceilings, pipes, cable trays, metal profiles, perforated strips, wire hangers, vernier hangers, wooden strips, wooden laths, square timbers etc.
- For use in reinforced or non-reinforced normal weight concrete with a concrete compressive strength of min. C12/15 and max. C50/60 in accordance with EN 206-1:2000-12
May only be used in dry indoor room conditions

| 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 and the influence of the edge distance and anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Appendix C. 2) The partial safety factors for load capacity when exposed to fire of γM,fi = 1.0, as recommended in the approval, and the partial safety factor of the effects of γF = 1.0 have been taken into account. | |||

| 3) Tungsten carbide hammer drill bits must comply with the specifications set out in the information leaflet of the Deutsches Institut für Bautechnik (German Institute of Civil Engineering - DIBt) and the Association of German Tool Manufacturers (FWI) on the "characteristic values, requirements and tests for masonry drill bits with tungsten carbide cutting body which are used for the manufacture of drilled holes for anchoring". Würth hammer drill bits meet the specifications set out in the information leaflet. | |||
