- Asymmetrical coarse thread with large threaded part (lg) for high tensile strength
- Large SW17 hexagon head with shaft reinforcement for high transmission of forces and optimum fit
- Integrated AW40 drive for flexible screwing
- Mating thread to reduce splitting forces
- Galvanised steel, blue passivated (A2K), without end mill
For safety reasons, the screws must only be used once.
The whole component should be connected with at least two wood screws. Ensure that the screws are not screwed into shrinkage cracks or similar.
For statically indeterminate suspensions with more than three strands, the anchors must be appropriately dimensioned so that two anchor points can hold the entire load. The loads on the anchor points must be calculated according to the triangle of forces. When positioning more than two anchor points (statically determined suspensions), appropriate measures (e.g. spreader bar) must be taken to ensure a uniform distribution of load over all strands.

ETA-11/0190
Expert reports
Ideal for transporting wooden components made from solid wood, board plywood, timber veneer and laminated timber
Always observe the specifications set out in the expert reports in conjunction with ETA-11/0190 and the relevant national regulations.
Applications:
- Axial force in panel surface or narrow edge of panel
- Oblique force in panel surface or narrow edge of panel
- Oblique force in panel surface with precision milled recess (d x t, 70 x 30 mm)
The thread of the screw must be fully anchored in the wooden surface without obstructing the component.
When screwing into the narrow edges of plywood boards, screw into the middle of a board layer. A transverse support must also be attached perpendicular to the panel surface around the screw fixings with ASSY plus FT full-thread screws.
When transport loads are applied, the transportation forces exerted on the transport anchor system must be taken into consideration in the form of vibration coefficients.
