Material Standards

The table below explains the abbreviations we use to denote the basic requirements for steels, aluminium alloys and copper alloys used in the manufacture of Avdel® fasteners. Each standard contains a list of grades available. The grade used for each range of Avdel® fastener is included in the general material and standard description at the top of our technical data sheets. Where the material used appears in more than one of the standards listed, as a direct equivalent, each grade is included in the description.

The inclusion of these standards and grade designations provides recognition of the material used in Europe, USA and worldwide. Using these designations it is also possible for customers to identify equivalent grades where they appear in their own national standards by reference to "Stahlschlüssel" or similar material databases.

Surface Finish Standards

The table below explains the abbreviations we use to denote the surface finish standards used in the manufacture of Avdel® fasteners, which provide recognition in the UK and throughout Europe. The general surface finish standard descriptions appear at the top of our technical data sheets along with the material standards detailed above.The term "yellow passivated" in relation to zinc or zinc/nickel plated fasteners refers to a supplementary treatment based on chromates to enhance the corrosion resistance.The absence of any supplementary treatment term for zinc plated fasteners indicates that they are supplied either with clear or no passivation.For fasteners that are not coated or are supplied polished, for example some aluminium alloy fasteners, the terms natural and polished are used respectively.The below table is an example listing for some of the standards available.
