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 the following purposes: – corrosion protection (as Type 1 coating); – lubrication, to facilitate insertion (as Type 2 coating); – withdrawal enhancement and/or collation for nails and staples (adhesive and/or resin coatings) (as Type 3 coating). 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 (see G.1); – staples (see G.2); – screws (see G.3); – dowels (see G.4); and – bolts with nuts (see G.5). 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.
