- In-place installation (M10 to M24) and pre-positioned installation (M8 to M24)
- High loads, minimum spacing and edge distances
- The bonded anchor is suitable for cracked concrete (concrete tensile zone) and non-cracked concrete (concrete compressive zone)
- The drill holes can be created using a hammer drill (W-VIZ M8 to M24), vacuum drill (W-VIZ M10 to M24) or diamond drill process (W-VIZ M10 to M24)
- Hardened chemical injection mortar largely seals off the drill hole
- Attachment with low expansion pressure allows minimum spacing and edge distances
- Geometry of anchor rod allows safe follow-up expansion capability
- Mechanical drill hole cleaning: Easy handling, very good drill hole cleaning, high loads
- Safe installation if the specified torque is applied when installing the anchor
- Force-controlled/torque-controlled expansion anchors made of stainless steel in sizes M8, M10, M12, M16, M20 and M24
- The load is transferred via the mechanical interlocking of individual cones in the injection mortar and also via a combination of retention and frictional forces in the base material (concrete)
Suitable injectable mortar: WIT-VIZ, WIT-VIZ Express

- The anchor has a European technical assessment for use in reinforced or unreinforced normal weight concrete with a concrete compressive strength of min. C20/25 and max. C50/60 in accordance with EN 206-1:2000-12
- Anchorage with European technical assessment in cracked concrete (concrete tensile zone) and non-cracked concrete (concrete compressive zone)
- Static (e.g. dead load, equipment, storage materials) or quasi-static (e.g. staircase railings) actions: M8 to M24
- Seismic effects, earthquakes (category C1 + C2): M10 to M24
- Anchor size M8 to M24: Installation in dry or wet concrete
- Anchor sizes M12 to M24: installation in water-filled drill holes (exception: W-VIZ-A 75 M12 - installation in water-filled drill holes not permitted)
- For use in concrete < C20/25 and pressure-resistant natural stone (without approval)
- W-VIZ/A4 (stainless steel A4) can be used in dry indoor areas, outdoors (including in industrial atmospheres and coastal areas) or in wet rooms
- Suitable for fastening metal structures, metal profiles, brackets, base plates, supports, railings, wooden structures, beams etc.
Clean the drill hole: 2x blow-out, 2x mechanical brush-out, 2x blow-out
If the drill hole is M20 or larger, blow out with pneumatic air using the appropriate pneumatic air nozzles
