Non-preloaded structural bolting assemblies - Part 1: General requirements
 N EN 15048-1

Annotation

This part of this European Standard specifies the general requirements for bolting assemblies for nonpreloaded structural bolting. Bolting assemblies in accordance with this European Standard are designed to be used in structural bolting connections for shear and/or tensile loading.

The intended use of bolting assemblies in accordance with this European standard is structural metallic works.

It applies to bolts (the term used when bolts partially threaded, screws, studs and stud-bolts are considered all together) and nuts made of carbon steel, alloy steel, stainless steel or aluminium or aluminium alloy with the following property classes:

— bolts made of carbon steel or alloy steel: 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9 (in accordance with EN ISO 898-1);

— nuts made of carbon steel or alloy steel: 5, 6, 8, 10, 12 (in accordance with EN ISO 898-2);

— bolts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO 3506-1);

— nuts made of austenitic stainless steel: 50, 70, 80 (in accordance with EN ISO 3506-2);

— bolts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839);

— nuts made of aluminium or aluminium alloy: AL1 to AL6 (in accordance with EN 28839).

This European Standard applies to bolting assemblies with ISO metric coarse pitch thread from sizes M12 to M39 for use in steel structures according to EN 1090-2, and from M5 to M39 for use in aluminium or aluminium alloy structures according to EN 1090-3. The use of thread sizes larger than M39 is not precluded provided all applicable requirements of this standard are met.
