Timber structures - Dowel-type fasteners - Requirements; German version EN 14592:2022

This document specifies the characteristics of the following types of dowel-type fasteners: nails; staples; screws; dowels; bolts with nuts. This document covers dowel-type fasteners for structural use in load bearing timber structures only. This document covers also the following additional intended uses of the screws: to fix roof or cladding elements to the timber structure, with or without insulation layers and as reinforcement inserted in timber or in a glue laminated timber element to improve its resistance to compression perpendicular to the grain. This document covers types of dowel-type fasteners, which are manufactured of either carbon steel or stainless steel and which may be coated for thefollowing purposes: corrosion protection; lubrication, to facilitate insertion; withdrawal enhancement and/or collation for nails and staples (adhesive and/or resin coatings). This document covers types of dowel-type fasteners, which are manufactured from materials and within the specifications for their geometry related properties, only as they are specified for: nails; staples; screws; dowels and bolts with nuts. This document specifies also the assessment and verification of constancy of performance (AVCP) procedures of these characteristics and includes provisions for marking of dowel-type fasteners. This document does not cover dowel-type fasteners treated with fire retardants to improve their fire performance, nor does it cover glued-in rods.
