Which Fas-ner is for You?

A FAS-NER® TO MEET YOUR NEEDS

The AKH FAS-NER® is made from hardened steel or aluminum and available in a range of twenty-one standard sizes. Material with a combined thickness ranging from 0.075 inch to 0.360 inch can be joined using the AKH FAS-NER SYSTEM®.

To determine the proper FAS-NER® size for your application, select from the chart the FAS-NER® which will most closely approximate the total thickness of the materials to be joined. AKH can customize FAS-NER® sizes to meet your application needs.

Example:

If you join one sheet of 18 gauge aluminum, which is 0.0403 inch thick, to a sheet of 16 gauge steel, which is 0.0598 inch thick, you will have a combined thickness of .1001 inch. The application would call for a #4 steel FAS-NER®.

The best joint strength will result from piercing the softest and/or the thinnest material first.

Steel FAS-NERS® are available with the standard zinc chromate plating at least 0.0003 inch thick. Zinc dichromate for increased corrosion resistance, as well as other platings and coatings are available on request to meet your requirements. FAS-NERS® can also be painter to match your prepainted materials, eliminating need for post-painting operations.

Insure that your material conforms to your specifications and tolerances before selecting the proper FAS-NER® size. A FAS-NER® oversized or undersized to the combined material thickness of the assembly can be used but may require modifications to the insertion dies.
