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

Quick, easy installation or dismantling by screwing the screw anchor in and out of the drill hole

Proof of Performance

European Technical Approval ETA-05/0012: Option 1 for cracked and non-cracked concrete

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

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.
