scope:

This part of this European Standard specifies the general requirements for the components of bolt/nut/washer assemblies for non-preloaded structural bolting and for the assemblies themselves. It applies to bolts (including screws, studs and stud bolts) and nuts made of carbon steel, alloy steel and stainless steel with the following property classes: - bolts made of carbon steel and alloy steel: 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9; - nuts made of carbon steel and alloy steel: 4, 5, 6, 8, 10, 12; - bolts made of austenitic stainless steel: 50, 70, 80; - nuts made of austenitic stainless steel: 50, 70, 80; - if appropriate, washers according to hardness class HV 100 or HV 200. NOTE: The property classes 4.8, 5.8 and 6.8 may be subjected to limitations of use, it is recommended to refer to ENV 1090 1. The standard applies to thread sizes from M12 to M36 and to the associated washers but does not preclude the use of other sizes. Bolted connections with components according to this European Standard are able to be shear and/or tensile loaded. Bolts, nuts and washers according to this European Standard are not normally intended for welding.
