- Anchoring by positive locking
- Through-hole mounting
- Immediate load-bearing capacity – no waiting
- Almost no expansion effect, enabling minimal edge and axial clearance to be maintained
- Quick, easy installation or dismantling by screwing the screw anchor in and out of the drill hole

Datasheets(X)
Individual attachment: Cracked and non-cracked concrete
With a European Technical Approval, the anchor may be used in reinforced or non-reinforced standard concrete of a strength class of at least C20/25 and at most C50/60 in accordance with EN 206: 2000-12
The anchor may be used for anchoring with predominantly static loads (e.g. tare weight, fittings, stored materials) or quasi-static loads (e.g. façades, railings)
Can be used in concrete < C 20/25 and hard natural stone (unapproved)
W-SA (galvanised steel) can be used in dry indoor areas
Suitable for attaching metal structures, metal profiles, brackets, footplates, supports, cable conduits, pipes, railings, wooden structures, roof beams, etc.
The saw-tooth threads cut into the concrete when the anchor is screwed into the pre-drilled hole
