For individual attachment in cracked and non-cracked concrete. Type S, hexagon head, galvanised steel.
- 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
- Large variety of types - Wide range of applications
- Quick, easy installation or dismantling by screwing the screw anchor in and out of the drill hole
Proof of Performance
- European Technical Approval option 1 for cracked and non-cracked concrete: ETA-05/0012
- Fire resistance (anchoring base: concrete from C20/25 to C50/60): R30, R60, R90, R120: Technical report TR 020 "Evaluation of anchorages in concrete concerning resistance to fire" (included in ETA-05/0012)

Application area
- 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.
- Anchoring with European Technical Approval in cracked concrete (tension zone) and non-cracked concrete (compression zone)
- 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 < C20/25 and hard natural stone (unapproved)
- W-SA can be used in dry indoor areas.
- Suitable for attaching metal profiles, pipes, ventilation ducts, wooden structures etc.
Instructions
The saw-tooth threads cut into the concrete when the anchor is screwed into the pre-drilled hole.
