High-performance stud anchors for highest loads in cracked and non-cracked concrete, stainless steel, A4

Highest load values at low spacing and edge clearances

Extra-large effective anchorage depths maximise the already high load values per anchor

Quick installation with fewer reinforcement hits

Extra-small effective anchorage depths minimise the drilling and setting time

Economical and flexible application

Freely selectable embedment depth allows optimum utilisation of the anchors depending on the embedment depth and application

Minimum edge distance and spacing

Allows for near-edge fixings, small anchor plates and installation in thin concrete parts

For earthquake-proof construction

High performance under seismic action, earthquake performance categories C1 and C2

¹⁾ The partial safety factors of the resistances regulated in the ETA and a partial safety factor of the effect of γF = 1.4 have been taken into account. Please refer to the European Technical Assessment ETA-20/0229 ²⁾ for information on combining tensile and transverse loads, edge influence and groups of anchors ²⁾ Use with anchoring depths h_ef< 40 mm is limited to the anchoring of statically indeterminate systems under the condition of dry interiors ³⁾ The concrete has normal reinforcement. Higher values are possible for higher concrete compression strengths
