  • 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.
