Individual attachment with approval
Normal concrete C20/25 to C50/60 (cracked and non-cracked concrete, seismic performance category C1 and C2 for sizes M8–M12)
e.g. metal structures, metal profiles, brackets, base plates, supports, cable conduits, pipes, railings, machines etc.
Individual attachment without approval
Can be used in concrete < C20/25 and compression-proof natural stone
W-HAZ/S approved only for use in dry indoor room conditions

| 1) The partial safety factors of the resistances regulated in the approval and a partial safety factor of the effects 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 concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. 3) For Würth W-HAZ-SK/S. | |||||||||
