- High load-bearing capacity, low centre to centre and edge clearance
- Immediate load-bearing capacity – no waiting
- Torque-controlled expanding anchor made from galvanised steel
- Safe expansion in cracked concrete owing to fixing anchor cone with patented plastic coating
- Countersunk screws ensure an elegant appearance for visible anchorages combined with high load-bearing capacity (e.g. railings)
- Also suitable for temporary anchorages (cotter-pin installation, e.g. flexible stadium seating – flush with surface to eliminate risk of injury)
- ETA-99/0011 for individual attachment, option 1, cracked and non-cracked concrete
- Fire resistance: R30, R60, R90, R120; Technical Report TR020 (included in ETA-99/0011)
- The W-FAZ-IG Fixanchor must be inserted using the appropriate approved setting tools (anchor system)
- Hexagon head bolt, countersunk head screws, washers, countersunk washers and nuts have a special coating and are only admissible in the anchor system in accordance with ETA-99/0011. Therefore, please order these separately
- Threaded rods may only be used if the conditions specified in approval ETA-99/0011 (material quality, dimensions, mechanical properties) are met
- The torque required for anchorage can be applied with Würth torque wrenches and suitable attachments (open-end socket spanners)

Individual attachment with approval
Standard concrete C20/25 to C50/60 (cracked and non-cracked concrete)
E.g. metal structures, metal profiles, brackets, footplates, supports, cable conduits, pipes, railings, wooden structures, beams, stadium seating etc.
Individual attachment without approval
Can be used in concrete < C20/25 and compression-proof natural stone
May only be used in dry indoor areas

| 3) 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. 4) The concrete has normal reinforcement. Higher values are possible for higher concrete compressive strengths. | ||||||
