Timber structures. Dowel-type fasteners. Requirements. | Status: Current

1 Scope 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.
