Basic Elements Fasteners

The elements in the “Fasteners” product group providepower-locking profile connections of extreme rigidity.The flexible screw attachment principle of all thefastening elements is of particular benefit when makingmodifications to the structure at a later date, easily allow-ing enlargements or reductions in size.item fastening elements are characterised by:

> Screw connections secured by means of the pre-ten-sioning effect in the flexible area of the groove flanks> The only tools required for assembly are standardhexagon keys> Several fastening elements can be used when largerprofile cross-sections are employed

1.3 Fasteners

The following table lists key features that will enable youto make the right choice when selecting from the largerange of fastening elements available from item.

Classified based by how the profiles fit together, it pro-vides details of the load-bearing capacity, any machiningthat is needed, and possible applications for each profileconnection.
