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.

EAD 130033-00-0603 Nails and screws for use in nailing plates in timber structures (12 pages ) Version: March 205; OJEU 2015/C 226/05; EOTA EAD 130118-01-0603 Screws and threaded rods for use in timber constructions (28 pages ) Version: February 2019; Decision (EU) 2020/962; superseding "EAD 130118-00-0603"; EOTA

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

Please feel free to use the template below.

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.
