- Quick and easy push-through installation using a tangential impact driver
- High transferable tensile and shear loads
- Loads do not depend on fixture thickness
- One screw size for all wood thicknesses
- Invisible sill fastening: The small screw head can be countersunk in the wooden beam
- Can be loaded immediately - no need to wait
- Almost no expansion effect, small edge distances possible
DIBt National technical approval: Z-21.1-1917: Anchoring of wooden components in concrete
Design
- Anchoring in concrete: Design in accordance with DIN 1992:-4-2019-04
- Anchoring in wood: Design in accordance with DIN EN 1995-1-1_2010-12 in conjunction with DIN EN 1995-1-1/NA:2013-08
taking into account the additions and instructions from Z-21.1-1917
According to approval Z-21.1-1917, the screw anchor must be processed with the appropriate setting tool and a suitable tangential impact driver.

Create the drill hole

Clean the drill hole

Adjust wood thickness [cm] on setting tool

Set screw anchor with tangential impact screwdriver

The screw anchor is correctly set when the marking [setting tool] is flush with the surface

For anchoring wooden components in cracked and uncracked concrete:
For example, for fastening wooden components such as sills, inferior purlins, beams, substructures etc. to concrete
- In static and quasi-static loads in reinforced or non-reinforced normal weight concrete with a concrete compressive strength of at least C20/25 and at most C50/60 in accordance with EN 206-1:2001-07
- Use in dry indoor conditions only
The screw anchor can be used to connect the following types of wooden components:

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 EN 1992-4. 2) The admissible value contains the failure type "head pull-through" by the wooden fixture "softwood C24" in accordance with DIN EN 1995-1-1. 3) d = angle between force and grain 0° means, for example, that the force acts in the direction of the grain (intermediate values can be interpolated). |
