Screws for timber construction
In timber construction, screws are used to permanently connect timber elements to other elements or to reinforce timber elements. In this work area, you will also find threaded rods and screws for external thermal insulation composite systems (ETICS).
Regulatory framework
DIBt grants national technical approvals (abZ) for screws that are not covered by the relevant harmonised standard, DIN EN 14592.
European Technical Assessments (ETAs) can be issued for screws that are not (fully) covered by DIN EN 14592.
For applications comprising screws for timber construction, DIBt grants general construction technique permits (aBG) when there is no conclusive technical rule for design and execution.

European Technical Assessment (ETA)
To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
