- High transferable tensile and shear loads
- Invisible sill fastening: The small screw head can be recessed in the wooden beam
- Several fixture thicknesses possible for each screw diameter (e.g. W-SA TC 12 x 160: tfix = 80 mm to 300 mm)
- Loads do not depend on attachment thickness
- Push-through installation
- Quick and easy assembly and removal - the sill anchor can be set with the tangential impact driver ESS ½ inch
- Immediate load-bearing capacity - no waiting
- Virtually no expansion effect, enabling minimal edge and axis distances to be maintained
- Anchorage via mechanical interlock
- The saw-tooth threads cut into the concrete when the sill anchor is screwed into the pre-drilled hole.

Datasheets(X)
Fastening wooden sills in cracked and non-cracked concrete
The sill anchor has general technical approval for use in reinforced or non-reinforced standard concrete with a strength class of min. C20/25 and max. C50/60 in accordance with EN 206-1:2001-07
Anchorage with general technical approval in cracked concrete (tension zone) and non-cracked concrete (compression zone)
The sill anchor may only be used for components in enclosed areas, e.g. homes, offices, schools, hospitals, retail outlets
The sill anchor can be used to connect the following types of wood:
- Solid wood made of coniferous wood assigned at least grade S10 in accordance with DIN 4074-1
- Laminated timber in accordance with DIN 1052
- Laminated beams assigned at least grade S10 in accordance with general technical approval

1) The partial safety factors of the resistances regulated in the approval and a partial safety factor of the actions of γF = 1.4 have been taken into account. For information on combining tensile and shear loads, on the influence of the edge distance, and on anchor groups, please refer to the European Technical Approval Guidelines (ETAG), Annex C. 2) The admissible value contains the failure type "head pull-through" by the wooden component "Softwood C24" according to DIN 1052:2008-12. |
