"Only use complete sets (screws, nuts and washers) from one manufacturer." (extract from DIN EN 1993-1-8/NA:2010-12).
The design of steel structures with high-strength fittings is regulated by DIN EN 1090-2 and DIN EN 1993-1-8/NA.
Storage and Transport
The screws, nuts and washers are supplied in a hot-dip galvanised design with nut lubricated under process conditions. The female thread of the nut is not hot-dip galvanised and is only protected from corrosion by the applied lubrication. Improper storage or transport conditions may cause corrosion of the female thread or a change in the condition of the factory-supplied lubrication, thus changing the relationship between tightening torque and pre-tension force.
